Is this on the nexus 7? There are some other issues that seem to affect this device only.

Yes, sorry I forgot to mention. This is on a Nexus 7 with 4.1.1.

I see this on my Galaxy Nexus, looks like a regression on Nightly. I wonder if it's anything related to (https://hg.mozilla.org/mozilla-central/rev/8357f094c300) from bug 761785.

I'll check for a regression-range.

Using the URL http://cnn.com and pinch-zooming outwards exposes this behaviour. 

My range is yielding

http://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=efb7823db78a&tochange=a76e0a267f26

Looks like bug 768440 or bug 755084 or bug 706179

I backed out the offending changesets:

[Mark Finkle (:mfinkle) (use needinfo?)]

Aaron and Snorp say the backout fixed the problem

Comment 9

[Boris Zbarsky [:bzbarsky]]

Any way we can add a test for this?
