I experience the same behavior with BTRFS subvolumes mounted by systemd mount units.
Not on every boot, but after a seemingly random number of boots the device id changed and Baloo indexes the subvolume all over again.

Looks good to me. Please increase the "version" number whenever you change an highlighting file.

Please, also add a test file in: "autotests/input/". To generate the files in "folding", "html" and "reference" use make test and autotests/update-reference-data.sh.

If you are only going to use the "admonition" keywords list for autocompletion, you could add them to the end of the context "section" or "start", keeping the attribute (Normal).

Fix diff.

Add test AsciiDoc.

• Drop unused 'admonition' keyword list.
• Rename itemData elements to start with capital letters.
• Enable escaping in block and section titles.

Running the katesyntaxhighlighting indexer tells me:

katehighlightingindexer::KeywordChecker::check: "syntax-highlighting/data/syntax/asciidoc.xml" Unused keyword lists: "admonition"

Could you fix this? Usually, keyword completion should be context dependent anyways (currently a bug), so soon your unused list will indeed not have any effect.

Drop custom colors and backgrounds.

I am not a reviewer, but I want to add some recommendations in relation to the itemData's:

• On lines 467, 476 and 485 you use harded colors for the fonts. Ideally, don't use them, but use the default styles, since a better visualization is achieved in the different schemes: https://kate-editor.org/2014/03/07/kate-part-kf5-new-default-styles-for-better-color-schemes/
• On lines 469 & 471 you use background color, and on lines 466-467, 473-474, 479-481 and 490 you use background color, but not font color. Try not to use background color if it's not necessary, to get a better visualization in the different schemes. However, if you need background color, it also specifies the font color, to avoid readability problems in some color schemes (for example, the background color &monospaced_bg; with dsNormal is not readable in dark schemes).

• Add missing allowed leading characters for links.
• Add escaping of attribute usage.
• Avoid highlighting of spaces inside table.
