The Bugbug bot thinks this bug should belong to the 'Core::Widget: Cocoa' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Could you please provide a list of websites where this is happening? Are you using any extensions that may be changing the browser's user agent string? Are you able to reproduce in safe mode (Help -> Troubleshoot mode...)?

I was seeing it at twitter.com, but that went away when I used safe mode.. The only other site/program I noticed it with was with crossword puzzles using PuzzleMe; e.g., the one here: https://www.newyorker.com/puzzles-and-games-dept/crossword/2023/11/06.
