In reader mode it is not possible to pan down when the finger is over an image. Panning upwards is possible. STR: 1) Visit http://m.wired.com/gadgetlab/2012/07/apple-reveals-for-monday-trial/ 2) Try to pan down with the finger over the image at the top Expected: Site pans down Actual: Nothing happens

Is this reader-mode specific? CC'ing :cats

(In reply to Aaron Train [:aaronmt] from comment #1) > Is this reader-mode specific? CC'ing :cats Yes, I can pan around fine on the original article.

The readability code appears to be mangling the page somehow so that the <a> tag wrapping the image has overflow: scroll set on it. Also for some reason the clientWidth/clientHeight of the <a> tag are 0, while the scrollWidth/scrollHeight are non-zero. This makes us detect that <a> tag as scrollable, and so we intercept all of those touch events and try to use them for scrolling the <a> tag, which isn't actually scrollable.

This is a bug in reader's CSS. I have a fix for it.

When I attempt to pan, my console floods with: I/GeckoSubdocumentScrollHelper(10060): Got message: Gesture:ScrollAck Using the URL: http://tantek.com/2012/222/b1/cole-valley-cell-tower-approved-planning-commission

This will be fixed as part of bug 766948.
