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

joshas, can you try using mozregression (https://mozilla.github.io/mozregression/) to help us track down when between versions 93 and 95 this was fixed?
Of course. Here are the results:
