Notes:
The rationale for the expected outcome here is described at
https://drafts.csswg.org/css-writing-modes-3/#valdef-unicode-bidi-plaintext
"Because the unicode-bidi property does not inherit, setting bidi-override or plaintext on a block box will not affect any descendant blocks. Therefore these values are best used on blocks and inlines that do not contain any block-level structures. "
