When viewing recent changes or the watchlist on Wikipedia, all the changes appear shifted below the bullets instead of to the right in the same row. This bug has been reported at https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical)#crazy_watchlist.
I think this is because the highlight container divs (added by T198139: Move construction of highlight containers to server) have no CSS rules hiding them in the old UI (non-RCFilters mode). In Chrome, the div containing these divs doesn't break the line even though it's display: block, and I don't understand why. I could easily understand Edge behaving differently (and all the reports on VPT are in Edge).
Please, folks, always include a screenshot. I couldn't reproduce this at first because I had enhanced RC enabled ("Group changes by page in recent changes and watchlist") and apparently the issues does not affect that mode. It would be obvious that I have to disable that if there was a screenshot.
So, here's a screenshot, for future reference:
