It seems this needs a Hulu account to repro, which I do not have. Can we have a reduced test case?

The <div class="Player__container addFocus" tabindex="0" aria-hidden="false" aria-label="Video Player" role="region" style="display: block;"> element has overflow:hidden, but is getting a non-zero scrollLeft, maybe via a focus call. I'm not sure why we allow overflow:hidden to scroll for focus.

Possibly the patch for https://bugs.webkit.org/show_bug.cgi?id=238985 fixes this.

I can test. Something that did surprise me was that we seem to be scrolling-into-view inside overflow:hidden. Not sure if that's intentional.

Comment 5 Simon Fraser (smfr) 2022-06-23 10:15:41 PDT

That patch did fix this.
