I tried many things, but wasn't able to reproduce the error
described in T283755. What probably happens goes like this:
* Somehow $this->refs[$group] is initialized, but
$this->groupRefSequence[$group] is not.
* There are not many places in the code where this can
happen. There are a few suspicious lines in rollbackRef(),
but they are all guarded. The only problematic place is in
appendText().
* This problematic line is only called for <ref> in
<references>.
* Somehow a <ref> is valid enough to make it to appendText(),
but not valid enough to make it to pushRef().
* The next time another <ref> is added to the same group, it
appears like the group already exists ($this->refs[$group]
is set), but $this->groupRefSequence[$group] is missing.
I was unable to find a wikitext example that would behave like
this.
This patch just makes sure the initialization is done but
doesn't care why it was missing. The following code is fine
with an existing ref that contains nothing but text (which is
how appendText() leaves it behind).

This patch also adds a test case that was missing before. If a
follow="…" is followed by another, normal <ref>, the internal key
(a.k.a. $this->refSequence) is not incremented. This was the case
before, just not covered by any test.

This removes a few tiny pieces of code, and a large chunk related to
incomplete follow="…" attributes (see T240858). It turns out we don't
need to insert elements at the top of the ReferenceStack::$refs
array, because this array is reordered anyway in
ReferencesFormatter::formatRefsList()!
Incomplete follow refs don't have a number, and are ordered to the top
because of this, as before. This doesn't change with this patch.

This exception was introduced very late in the patch I38c9929. It
already caused trouble. This here is essentially a revert. It restores
the previous behavior where this edge-case was silently ignored. The
worst thing that can happen is that appendText() creates an incomplete
entry in the $this->refs array, which will be rendered at the end. The
user can see it then.
As of now we are not aware of a code path where this would even be
possible. Still this does make the code *more* robust by not making it
explode, but give the user something they can work with.

* Always have an empty line between @param and @return to improve
readability as well as consistency within this codebase (before, both
styles have been used).
* Flip parameter order in validateRefInReferences() for consistency with
the rest of the code.
* In Cite::guardedRef() the Parser was now the 1st parameter. I changed
all related functions the same way to make the code less surprising.
* Same in CiteUnitTest. This is really just the @dataProvider. But I feel
it's still helpful to have the arguments in the same order everywhere, if
possible.
* Add a few strict type hints.
* It seems the preferred style for PHP7 return types is `… ) : string {`
with a space before the `:`. There is currently no PHPCS sniff for this.
However, I think this codebase should be consistent, one way or the other.

There is currently no strict CodeSniffer rule for this. I think we
need to have one sooner or later. Anyway, what I find important is to
have a consistent code style in one codebase.
I refused to do this change previously because I don't like to mess
with Git blame if it's not really necessary. However, at this point all
code was moved around anyway.
I ended removing a comment that appears misplaced now, and doesn't help
maiing the code more readable. I like not having a dot at the end if
it's not really a sentence.

In the end I don't care much if we agree on having this newline, or
not. What I care about more is that this codebase is consistent.
Personally I prefer having the newline. It creates a visible separation
between what "goes in" and what "goes out" (@throws and @return).

The rollback feature was not able to properly restore a __placeholder__.
That's why a specific use case was behaving different. This already
worked just fine:
<ref extends="a">…</ref>
<references>
<ref name="a">…</ref>
</references>
But this didn't, even if it is the exact same from the users
perspective:
<ref extends="a">…</ref>
{{#tag:references|
<ref name="a">…</ref>
}}

Note this leaves *another* bug behind. When a <ref> is properly reused
by name="…", and the content is fine (either missing or identical),
possibly conflicting extends="…" attributes are currently entirely
ignored. However, this is already much better than what happened before.

The rollbackRefs function no longer needs to "know" details about
how to turn a refCallStack item into a redo item. This is better a
responsibility of the subroutine, where the items are unpacked.

One of the most significant changes is when I noticed that the $group
can never be null. We set it to DEFAULT_GROUP before. That's an empty
string.
I'm not very happy with the two @phan-suppress-next-line. Is there a
better way to fix these lines?

These should be impossible conditions, we don't want to continue with
processing.
I hate this patch, it's a temporary workaround until someone rewrites
or replaces the rollback logic, for example with a two-pass parse.

I hope this patch is not to horrifying and can be reviewed. It's
possible to split this into a sequence of smaller patches. Please
tell me.

The main benefit is this nifty call: `$this->rollbackRef( ...$call )`
To make this possible, the minimal change I needed to do was to move
the two $argv and $text arguments to the end.
I also tried to order all other arguments as good as I could: Required
first, optional later. Group and name together. Name and extends
together.
All this is private implementation and should not affect anything.

I feel this is a little better than before. It looks like we never need
to *replace* a text that existed before.
This depends on I4a156aa which fixes one of the last remaining trimming
issues. Outside of <references>, a <ref> </ref> with no other content
but some whitespace was already forbidden. But not inside of <references>.
This is relevant for appendText(). It should not be called with null, but
was because of the inconsistent behavior.

* Use the Html class to safely create HTML code.
* $this->referenceStack can not be null any more.
* $this->inReferencesGroup is not needed during output, only when
parsing tags.
* Replace ReferencesStack::getGroupRefs() as well as deleteGroup()
with a combined popGroup() that does both things.
* Extract the code responsible for the "responsive" behavior to a
separate function.
* Some TestingAccessWrapper are not needed.

Finishes breaking the circular reference between Cite and Parser.
This patch also demonstrates how evil it is to allow the error reporter
to be called from anywhere, and have side-effects. At least it's explicit
now.
Also fixes a bug where the inner error message would not be in the
interface language.

Only create a Cite object if we need one. Never clearState, just
destroy and recreate later.
This makes it less likely that we leak state between parsers, and
saves memory and processing on pages without references.
It's also preparation to decouple Cite logic from state.

* All classes are in a Cite\ namespace now. No need to repeat the word
"Cite" all over the place.
* The "key formatter" is more an ID or anchor formatter. The strings it
returns are all used in id="…" attributes, as well as in href="#…" links
to jump to these IDs.
* This patch also removes quite a bunch of callbacks from tests that
don't need to be callbacks.
* I'm also replacing all json_encode().
* To make the test code more readable, I shorten a bunch of variable
names to e.g. $msg. The fact they are mocks is still relevant, and still
visible because these variable names are only used in very short scopes.
