The web team doesn't maintain FlaggedRevisions and my understanding is that extension is more or less frozen, so fixing this will be.. interesting :)

Obligatory links: T185664: Code stewardship review: FlaggedRevs and T277883: Drop all low-use and unused features of FlaggedRevs to make it more maintainable

Note that this is one of four possible UI of FR. I think this is lowProfile set to False I think. You probably need to check the rest of them as well

Consolidating these options and reworking the design of it would be amazing (to simplify the code). I always recommend to look at FR and its features/UI/code through the lens "What can I remove or simplify?"
