I find this particularly confusing because it makes it look like this is
an array. As a reminder, while empty arrays are false in PHP they are
not in JavaScript. An extra `if ( array && array.length )` is really
critical. But this is a string. Empty strings are false in JavaScript.
No problem.
This was originally written in 2013 via Ib244ff6 as a pure .length
check. The duplication was added a year later via Id401d97 for an
unknown reason.

Note these are more meant as regression test to better cover what's
done in other patches. Everybody should feel free to delete a test
when it gets in the way. I marked a few especially fragile places
with respective comments.

This CSS exists since I2ab47e7 from August 2014. The original idea
was to dim the default "General references" when you edit a <ref> or
<references> list in VisualEditor.
Steps to reproduce:
* Start VisualEditor.
* Edit a <ref> or <references> list.
* Edit the group.
* You will see the dimmed text "General references". This is not the
CSS in this patch, but the default styling for OOUI placeholders.
* Open the dropdown. The list will show a "General references" item.
It's not dimmed. This is where the CSS was meant to be.
The CSS class name in the OOUI mixin was actually changed from
"oo-ui-flaggableElement-…" to "oo-ui-flaggedElement-…" via I1abecd8,
just a few days later.
In addition the selector wouldn't work anyway for other reasons.
The dropdown is not inside the `.ve-ui-mwReferenceGroupInputWidget`
container any more but placed outside by the OOUI window manager.
And the selector's specifity is to low, at least since Ic57b3ff.
I argue it's not worth fixing it. Nobody missed it for 10 years.
Light gray text would be illegible anyway on the light gray/light
blue backgrounds used in the dropdown menu. Let's consider it dead
code and just remove it.
The class name doesn't appear anywhere else (any more):

This can be quite confusing:
* A node does have attributes. One of the attributes is called
"refGroup", another one "mw".
* mw contains a JSON structure with just a few elements, most
notably a "body" and an "attrs" element. These reflect what was
originally written in the wikitext.
* mw.attrs reflects the original properties a.k.a. attributes from
the <ref …> or <references …> tag.
Deleting mw.refGroup doesn't do anything because the attribute is
called <ref group="…"> in the wikitext, not <ref refGroup="…">.
You can actually see this bug in action on all wikis: Go to a page
that uses references in non-standard groups, e.g.
https://en.wikipedia.org/wiki/Historic_Cherokee_settlements
Start VisualEditor. Find e.g. the [notes 1] reference. Edit it
and change the group from "notes" to "General references". Click
"Publish…" and "Review" your changes. The visual diff works because
it apparently uses other information. The wikitext diff is empty.
This is also what's saved: nothing. The edit is lost.

This didn't mean what it looked like: `||` has higher priority, so an
undefined elem would not result in an empty string.
