673138 - Can't scroll contents of the iframe when main page is scrollable too on certain zoom levels

Status: RESOLVED WORKSFORME

(Firefox for Android Graveyard :: Panning/Zooming, defect)

Description

Attachment: testcase

See testcase, scroll down, there you see a scrollable iframe and a scrollable div.

I'm trying to scroll down in the iframe and the scrollable div, but I'm unable to in current trunk builds of Fennec on desktop.

On Fennec trunk on my mobile phone it seems to work, though.

I don't know why it doesn't work on Fennec desktop. Shouldn't Fennec desktop act the same as Fennec mobile?

Anyway, another problem I'm seeing is that if I zoom in considerably, then panning the iframe and the scrollable div isn't working anymore. I can pan the iframe and scrollable div when panning at a certain spot under them, though (there seems to be some logic flas somewhere, regarding zooming).

It turns out that I can scroll the iframe and scrollable div just fine while panning a little above the iframe and scrollable div.
So this has everything to do with the zoom level of the page.

I've noticed some issues about iframe scrolling on Fennec for different zooming levels as you can see here: http://www.youtube.com/watch?v=b_ogmAI-dho&feature=player_embedded

No, that bug was about the complete lack of iframe scrolling in multi-process Fennec, which is fixed.  This bug is about iframe scrolling breaking or behaving weirdly in specific circumstances.

Mass resolving XUL Fennec I filed to WORKSFORME. If someone still cares about this bug, please reopen.
