Steps to reproduce:
1. Load details page for an app with with big screenshot thumbnails on your Android device (ex. https://marketplace-dev.allizom.org/app/youzeek/ )
2. Swipe through screenshots.
3. Observe the third screenshot.
There are no design or layout issues.
The third screenshot goes over the description when swiped.
Verified on FF20 (Android 4.1.1).
Attaching screenshot for this issue.
Is this a <video> thing?
It's actually a screenshot thing when the height of the screenshot is greater than its container...the SS attached just happens to show a video so it's misleading.
The real fix for this would be if FF for android respected z-index while using GPU acceleration...I'll see if there's anything we can do from our end.
My fix comes in a strange vial labeled 'wonder tonic' but meh:
Verified as fixed in https://marketplace-dev.allizom.org/ on FF20 (Android 4.1.1 Galaxy Nexus)
The screenshot does not get out of the container anymore when swiping.
