Log Message:
-----------
Floats and inline-blocks are sized incorrectly when a child sets min-width:
min-content or max-content

<div style="display: inline-block">
<div style="width: 200px; min-width: min-content; max-width: 50px">
<div style="width: 60px"></div>
</div>
</div>
The middle box is 60px wide, but the inline-block around it is 200px.
computeIntrinsicLogicalWidthContributions() sets both contributions to the
fixed inline width, so the
keyword minimum reads back 200px instead of the content size. The maximum
already recomputes for this
case; make the minimum do the same and share the check.
