A TreeWalker ends up walking potentially every single subsequent
node in the document looking for a target node. Instead use upwards
traversal to find a common ancestor, then sibling traversal to
compare document order.
This makes calling cloneContents on every comment on a 300k talk page
significantly faster, going from >30s to 500ms locally.

Ideally the edit autosummary would be generated in the same
way as in the old wikitext editor: from the wikitext of the
heading. But on the JS side, we don't have access to the
wikitext, or to the PHP method that generates autosummaries.
This might seem crazy at first, but ultimately the point of
the autosummaries is to link to the section heading by its
'id' attribute, so it is perfectly reliable.
Doing it this way depends on $wgFragmentMode being set to
[ 'html5', 'legacy' ] or [ 'html5' ], otherwise the escaped IDs
are super garbled (particularly in non-Latin-alphabet languages)
and can't be unescaped reliably. Conveniently, we already
require that since 9ee0fd69f5.

It's an expensive method, and we previously called it for
every child of the common ancestor, completely unnecessarily.
These changes follow from two observations:
* If there is a $firstPartiallyContainedChild, then the
first fully contained child must follow it; similarly,
if there is a $lastPartiallyContainedChild, then the
last fully contained child must precede it.
* All nodes between the first and last fully contained
children are also fully contained.

This is not necessary, and never has been. This variable contains an
object and it's never assigned to.
Instead, the reference creates hard-to-debug bugs (I've just spent
an hour debugging one). When the variable name is reused later in
the same function as the loop variable of another foreach() loop
(such as in If918bfd5e0), the result is overwriting of the last entry
in $this->threadItems with the last entry from the other array.

The JS code worked correctly because it uses UTF-16 strings, so the

In JS, strings are internally encoded as UTF-16, and properties like
.length return values in UTF-16 code units.
In PHP, strings are internally encoded as UTF-8, and we have the
option of using methods that return bytes like strlen() or UTF-8 code
units like mb_strlen().
However, the values produced by preg_match( …, PREG_OFFSET_CAPTURE )
are in bytes, and there's nothing we can do about that. So let's use
bytes throughout, mixing the two types results in meaningless numbers.
Then in the test code, we have to calculate UTF-16 code units offsets
based on the UTF-8 byte offsets.
We also have to copy the entire workaround for mw:Entity nodes… Maybe
the parser should be fixed to return the real nodes for ranges' ends
in this case.
