It's a bug in webkit which doesn't sent out the right events when scrolling on the trackpad https://bugs.webkit.org/show_bug.cgi?id=210071. Currently we couldn't figure out the difference between mouse move and scroll.

@rebornix could you update the issue's title to capture that it's not only impacting trackpad support but also mouse wheel? I do not have the permissions to do that (:

Also, it is my understanding this is the main issue tracking this work (we're also tracking it on the Codespaces side).

@VincentDondain thanks, I updated the title.

Also, do know that while I can't comment on the timing of fixes, I am absolutely aware of this and know that it is important.
