Bug 226981 – [css-grid] Overflow should be computed with the actual logical bottom

• Component: CSS
• Status: RESOLVED FIXED

In order to compute the overflow area in the grid container we should
use the result of the ClientLogicalBottom function.

Looks like we're failing 7/14 subtests. Question is what was the status before the patch?

I have just noticed that in chromium  with NG enabled all tests have now passed. I need to look into this and update the patch.

I am not sure the fix is correct. Furthermore the patch seems to fix some cases but regresses some others, so I am not sure we're improving here.

The fix is not complete. Still I need to address the difference caused by paddings.

I like the idea, but perhaps we could do some refactoring between the clientLogicalBottomAfterRepositioning and the new logic you've added into the computeOverflow function. After all, it's the same logic for both inline and block axes, isn't it ? We could do both (when needed) in the same loop. What do you think ?

This function can be 'const', right ?
