Created attachment 355053 [details] Test case to reproduce the issue Steps to reproduce the issue: 1- load the attached test case What is the expected behavior? The inline elements are aligned using their baseline so that they match perfectly with the absolute positioned elements rendered under. There should be a completely filled black 100px square and no red should be visible at all. What went wrong ? Several tiny (1px) red lines are visible, despite the offsets got from the insect indicate that the inline and absolute positioned elements should match perfectly.

I've been unable, so far, to find out a test case to consistently reproduce the issue.
