I wonder whether we have to do the same with borders and/or position. But that's just food for thought for another bug.

Note the border is the one of the grid container. So it already is resolved using the writing mode of the grid container.

Oh right. But it still stands for the childPosition right?. There are several WPT tests failing in flexbox for example related to vertical-rl due to incorrect offsetLeft and I suspect that might be the cause of issues. Not sure if also here for grid too.
