Created attachment 444137 [details] testcase When clip-path is applied to an element, the content below the clipped part of the element cannot be scrolled, instead nothing happens. See the attachment. Scrolling below the purple square should trigger scroll underneath, but nothing happens. Note that other events (CSS hover and click) seem to work fine.
This might be bug 214367
<rdar://problem/85634077>
Is there any update on this? This is a pretty bad bug and a substantial issue for me.
Pull request: https://github.com/WebKit/WebKit/pull/8896
@Bruno Stasse I've encountered exactly the same problem and found a strange solution. Adding a wheel event to the clipped element somehow solves this. https://codepen.io/satoshionoda/pen/yLqvXrW I suppose this is quite hacky but can be used until this bug is completely solved.

That makes sense because wheel event handlers kick WebKit off of the fast path.
Ha that's quite interesting, thank you Satoshi Onoda! Unfortunately I need it to work on iOS, and there is no wheel events there so it doesn't work. If anyone has another workaround for iOS it would be very much welcome.
