WKWebview doesn't respond to click events when multiple fingers are used

If we use webView.loadFileURL(indexURL, allowingReadAccessTo: readAccessURL) on an iPad it loads the data and navigation works. But if we place two hands on top of the screen and move a bit, all click events are not working anymore.

It works again if we call loadFileURL again.

We filled a bug report: FB19812304
