Expected results: The element with scrollbars should scroll up and down as appropriate. Actual results: Nothing happens.

Normally they are. Not sure what is different about this layout.

Dave, you're right. I mistakenly thought that I had seen this on simpler sites. I will work on a reduction.

Created attachment 11141 [details] Reduction Reduction showing the bug. The magic ingredient is the "overflow: hidden" on the body element.

One further note: if the "overflow: hidden" is set on a containing div rather than the body, the scrolling works as expected. When set on the body, it doesn't.

This looks to happen because when the body element has "overflow: hidden", -[WebFrameView allowsScrolling] ends up returning NO due to it's WebDynamicScrollBarsView has horizontal/vertical scrolling modes set to Off. This causes -[WebFrameView keyDown:] to bail out of its handling of the key event and pass it up to super.

I am not able to reproduce this bug using attached "Reduction" in Safari Technology Preview 152 and upon clicking on "article" (grey box / area) and then using keyboard arrow guys, I am able to scroll up and down fine and it is matching with all other browsers (Chrome Canary 107 and Firefox Nightly 106). I am going to mark this as "RESOLVED CONFIGURATION CHANGED". Please reopen if you think this is not fixed. Thanks!
