Not sure which mistake I made... I think it's worth trying. You're adding 2s of tests, and that's not a sustainable rate.

The thing is that I was not sure whether I made something wrong in my attempt attachment 366274 [details] as the change makes the test then fails when I tried the other day. Not sure why they pass with the other API.

I'm still not able to make them pass with the internal APIs so I'll move this to a separate bug and handle the other tests here.

Created attachment 368236 [details] Patch (alternative version using immediateScrollElementAtContentPointToOffset) With that version, the tests fail for me.
