The primary patch in bug 1308876 causes frames to be reflowed less often with NS_FRAME_IS_DIRTY, particularly when multiple passes of reflow are required for the frame or one of its ancestors (which is generally the case for a document that ends up not having scrollbars). This change causes this assert to fire on various SVG tests such as layout/reftests/svg/svg-integration/conditions-outer-svg-01.xhtml . This happens because the outer SVG with conditional processing (in this test, systemLanguage="x") is reflowed due to its parent resizing, without NS_FRAME_IS_DIRTY set. This is a relatively normal thing to happen during reflow; we just didn't have any tests that exercise it. This patch adds a crashtest that triggers the assertion through the same mechanism, but with a dynamic change, rather than depending on the non-dirty reflow triggered by bug 1308876. (I confirmed locally that this test does trigger the assertion without this patch, when run in the crashtest harness.) I think fundamentally the assertion isn't valid, and we should instead be testing the condition that it asserts.
