Created attachment 374005 [details] Example of problem Using -webkit-overflow-scrolling: touch; in a container doesn't work properly frequently if you do single/double tap on content. Apparently the focus is moved to the body and the scroll on the correct container freezes. It's necessary tap/click again to return the focus to the correct container. The problem doesn't happen if I move the overflow-scrolling to 'auto' but the scroll will be not smooth. The problem happens on iOS 12.2 and 12.3. I have tried to use the pointer-events but the problem persists.
