I submitted a patch before filing this task: https://gerrit.wikimedia.org/r/c/mediawiki/extensions/WikibaseLexeme/+/902850

I tried to figure out where this CSS rule came from, but didn’t find much in T165567 or T160053; my suspicion is that the design screenshots, e.g. in T160053#3344681, happened to use initial-uppercase labels for the buttons, and that Aleksey added the text-transform: capitalize to match this, but that it wasn’t really a conscious decision at any point.

Maybe @Lydia_Pintscher or @Sarai-WMDE can make a quick decision here? (Technically, the patch looks fine and should be ready to +2 at any time.)

That sounds like a reasonable explanation, but we definitely make sure that:

The capitalization or non-capitalization of strings like this must be left up to the translators.

As mentioned in the task description. So, LGTUX.

+1
