It's unfortunate that WebKit hasn't implemented `touch-action: none` (https://bugs.webkit.org/show_bug.cgi?id=133112), which was the recommended way of dealing with this change when it was rolled out in Chrome.

* https://bugs.chromium.org/p/chromium/issues/detail?id=639227
* https://github.com/WICG/interventions/issues/18
* https://tech.slashdot.org/story/17/11/08/1135240/how-chrome-broke-the-web

As you can see from the above links, that roll out caused a lot of developer angst, to put it mildly. Now WebKit is rolling out a similar change, but one that requires a different work around?

I agree with Steve that this is likely to be a significant compatibility issue.
