They still used old 1.18-style diffs, with styles copied from core.
Also:
* Remove the distinction between "simple" and "multiline" diff chunk,
enabling consistent styling
* Always show word-level diff, even in previously "simple" chunks
* Ensure the full context is always shown. This was clearly intended
(showing straight side-by-side comparison if there were no changes
and in "simple" chunks, diff otherwise; showing chunks with no
changes), but the default context is only 2 lines.
* Remove the distinction between 'wikitext' and 'text' diffs (all are
treated like 'text' was); it's impossible to show parsed code with
word-level diff, and it was only enabled for "simple" chunks, all of
which are intended to be one-line strings and are shown unparsed
elsewhere (e.g. filter description on the list on Special:AbuseFilter)

Removed the redundant clss mw-abusefilter-examine-syntaxerror
as it was causing trouble because the syntax checker in
ext.abuseFilter.edit.js wasn't aware of it.

Was broken by r81905 consolidating background-repeat and background-position into a single background rule, which implied a 'background-image: none' overriding the background-image values set by other rules.
Restored them & added a comment so the next person won't do the same.
Also moved the image files to match the reorg of the css in r95572, which would have broken these images if r81905 hadn't done it first. ;)
