Can you provide some more explanation of what you're trying to do here?

Well, I just wanted to report the issue. I implemented some reference layout tests for the grid layout Baseline Alignment feature that are based on inline-blocks. However, there are tiny pixel differences in some case when combining different writing modes.

The patch just adds some simplified cases that should, IMHO, be rendered identically, but as the bots shown there are some differences. This issue is also reproducible in Blink, but only in Mac platform.
