-----------
Layout of inline-block vertical-rl differs from other browsers
https://bugs.webkit.org/show_bug.cgi?id=309408
<rdar://problem/171952790>
Reviewed by Antti Koivisto.
Margin box height is used as the synthesized baseline when the atomic inline box
does not have a content-derived baseline
<div>
text
<div style="display: inline-block"><div></div></div>
</div>
vs.
<div>
text
<div style="display: inline-block">has content-derived baseline</div>
</div>
In both cases, we look inside the inline-block to check whether there is content
that we can align the text with. While we find eligible boxes (text) in the
second case,
the first case returns empty, and we fall back to the margin box of the
inline-block.
However the final, synthesized baseline in vertical mode is the ideographic
central baseline.
