--- Comment #7 from Wenson Hsieh <wenson_hsieh at apple.com> ---
I’ve begun to investigate this.

One interesting thing I noticed is that the bug only seems to reproduce if the viewport is not responsive; adding something like:

<meta name="viewport" content="width=device-width, initial-scale=1">

seems to make the problem go away (at least, until the user manually pinches to zoom in).

This seems like bad interaction between the relatively new deferring gesture recognizers (WKDeferringGestureRecognizer) and the blocking double tap gesture recognizer (used when fast-clicking is disabled).
