Bug ID: 185001
Summary: Click events on outer page are not being dispatched
correctly after touch-zooming within an iframe
Product: WebKit
Version: Safari 11
Hardware: iPhone / iPad
OS: iOS 11
Status: NEW
Severity: Normal
Priority: P2
Component: HTML Events
Assignee: webkit-unassigned at lists.webkit.org

Iframe Zoom Click Repro
The attached file has an anchor labelled "Click Me" containing an onclick attribute of "alert('Clicked');", as well as an iframe sourced to a youtube video.
Repro:
1. Focus the video in the iframe
2. Zoom In
3. Zoom Out
4. Click "Click Me" on the parent page
Expectation: "alert('Clicked');" is executed and an alert box displays
Observed: The click event only seems to dispatch (and the alert box display) a fraction of the time.
Anecdotally, although the link should be at position 0,0 during all of the steps above, document.elementFromPoint(0, 0).click() also fails to result in a dispatched click event to the anchor element during the zoom operation as well.
