Probable this revision (r110073) caused by the timeout.
Thanks for your bug report.
With regard to this issue, we have not been able to see a resizer at the bottom-right corner when we open this file. When I bisect our snapshots, this issue starts from Chromium snapshot r125525 (*1). Unfortunately, this Chromium issue still happens even when I locally roll out my r110073. (In my honest opinion, my r110073 changes the position of the resizer only of an RTL element, i.e. it should not affect LTR elements used in this file.)
To read our change log (*2), r110072 (*3) also changes RenderLayer and I would like to hear the thoughts of Julien.
It is skipped on Qt until proper fix - http://trac.webkit.org/changeset/110276/trunk/LayoutTests/platform/qt/Skipped

That is an (unintended) consequence of my change. The resizer is attached to the RenderLayer which we don't allocate as we have no layout overflow. The fix is to patch RenderBox::requiresLayerForOverflowClip to return true if style()->resize() != NONE.
Now that doesn't explain the timeout which is AFAICT unrelated.
For the record, bug 80738 fixed the issue with the resizer not being present. As I don't know if the timeout is related to that, I haven't re-enabled the test on Qt.
When I build Qt WebKit r111496 on my Ubuntu (11.04) PC and run this test on it, this test finishes without any errors or timeouts. Is it possible to re-enable this test and see it still fails?
It passes now, unskipped by http://trac.webkit.org/changeset/111514
