902546 - IFrame contents rendering outside iframe boundaries (related to positioning: absolute?)

Status: VERIFIED WORKSFORME

(Core :: Layout, defect)

Description

[:Gijs (he/him)]

Reported over IRC, broken in OS X and Windows, Fx 23 as well as Nightly. Test page:

This can probably be narrowed down (as testcases go) but I don't have time to do that right now...

Note that toggling position: absolute off on the #subSurfacePanel div from the web inspector allows the content to be properly constrained to the iframe.

Regression window (m-c Linux64 builds): 2013-04-05-03-09-18 -- 2013-04-06-03-09-22

so it's likely caused by bug 841192.

Note that scrolling a bit seems to clip it (at least in Nightly Linux64).

Gijs Kruitbosch: Thanks for adding this bug, hope it will be fixed soon.

For me it does not fix the problem when I disable the position:absolute.. If I turn off the position:absolute it fits a bit better, but is still outside the iframe.. After scrolling a bit up and down it looks fine, but after waiting for 5 seconds it is again outside the iframe.

Using the attachment 787110 [details] from Mats, the bug can be fixed when you disable backface-visibility on the div with class front.

Tracking for branches as this is a recent regression and passing on to :roc for help with investigation given this may be a fallout form 841192

[Lukas Blakk [:lsblakk] use ?needinfo]

We don't have any indication right now that this is impacting a large amount of sites and given comment 6 has a workaround, not tracking for 23.

The comments in bug 906199 say this should now be fixed (by bug 906199).
