We never expected layout state to be enabled while calling mapAbsoluteToLocalPoint() during layout. Actually, calling mapAbsoluteToLocalPoint() during layout is just wrong, because layout isn't done yet; the mapping may give back the wrong answer.

Bug 70422 has alternative steps to reproduce. Do we know when this started, or what the release build symptoms are?
