1878846 - [css-grid] Baseline aligned items should join the correct sharing group according to writing mode

Status: RESOLVED FIXED

(Core :: Layout: Grid, defect, P2)

Description

[Tiaan Louw]

https://drafts.csswg.org/css-align-3/#baseline-terms

The baseline alignment preferences of two boxes in a baseline-sharing group are compatible if they have:
- the same block flow direction and same baseline alignment preference
- opposite block flow direction and opposite baseline alignment preference

This avoids using raw integer values which might cause bugs.
Also removed a clang-format: off block for better formatting.

Attachment: Bug 1878846 - Take writing mode into account when calculating baseline sharing group. r=#layout

https://drafts.csswg.org/css-align-3/#baseline-terms
The baseline sharing group is not equal to the baseline specified for
the item. It has to be calculated separately. The baseline sharing
group determines on which side of the block the item is aligned, but the
specified baseline is still used to determine the baseline of the item.

Depends on D200767
