Layout test fast/images/move-image-to-new-document.html is failing since http://trac.webkit.org/changeset/102829 (the fix for https://bugs.webkit.org/show_bug.cgi?id=74533).
The failure mode is that the load handler for an object element is not firing when the element is moved from one document to another. This seems like a regression that might have potentially large side-effects. Marking as Major severity for this reason.
Updated GTK test_expectations accordingly as well.
*** Bug 74607 has been marked as a duplicate of this bug. ***
This was lost in the failure noise before I landed. Will either come up with a fix or revert.
