I can reproduce this on Firefox 146.0.1, Android 13:

Setting a filter navigates to e.g. https://en.wikipedia.org/wiki/Special:EditWatchlist?namespace=2. If I then add paginate=1 again, the entries are filtered (e.g. https://en.wikipedia.org/wiki/Special:EditWatchlist?namespace=2&paginate=1). But clearly that's not how it's supposed to work.

Taking a shot at this one.

I figured this had just been forgotten, considering dark mode is otherwise already enabled on English Wiktionary. If this is intentional, though I can't immediately think of a reason why it might be, I'll wait.

Also affects Vector, Monobook, and Timeless. Only Vector-2022 seems to be unaffected.
Additionally, the position of the dollar sign as the first character doesn't seem to matter; cf. https://en.wikipedia.org/w/index.php?title=Wikipedia:Help_desk&oldid=1224959912#Dollar_sign_in_section_header, where it has been observed in the middle of a word.

Accessibility is a good point I hadn't considered; a comparatively tiny highlight only covering the footnote text itself might not be as easily visible.

Yes, this accesskey works on Vector 2010, i.e., it navigates to the watchlist; it also works the same way on Monobook and Timeless.

@Dbrant Maybe you're already doing that, but just in case: I think the "Undo" button should also be greyed out/hidden, since you can't exactly revert a page creation. Other than that, I think this looks very good.

I don't really understand what you mean, either, so I'll just try to explain what I mean in a different way.

I think it might also make sense to display revert notifications for edits remembered by the app similar to #1. Maybe just for reverts with an edit summary different from the default (the assumption being that a non-default revert summary might explain what's wrong with the reverted edit), if that's possible to determine.

From skimming c:User:Helix84/gallery, where a bunch of images fail to load in this way, it looks like most or all of the affected images have names of the form Young Folks' History of Rome illusNNN.png, where NNN is a three-digit number. Also, I get the occasional 500 for these images as well, but very rarely.
