Created attachment 417251 [details] touch-action: pan-y on body element This is similar to (and possible duplicate of) https://bugs.webkit.org/show_bug.cgi?id=198708, but I have not been able to reproduce that particular issue. When the `body` element has `touch-action: pan-y`, the user is able to pinch-zoom during momentum scrolling. See attached case _body-touch-action.html_ and _body-touch-action.mp4_. The issue does NOT reproduce on an element other than `body` (see attached case _element-touch-action.html_).
