Bug 1458598 - Override scrollframes with their descendant reference frames. r=mstange The test case has a fixed item A inside a scrollframe B which is inside a reference frame C which is inside the root scrollframe D. The ClipManager code currently uses D's scrollid as the scrolling ancestor for A, because the gecko display list's ASR is set up that way. However, we really want to set C as the scrolling ancestor, because otherwise the item A gets hoisted out of C and the transform from C doesn't get applied to it. This patch ensures that when we enter C, we install an override so that anything that would have used D's scrollid ends up using C's, which results in the correct behaviour.
