David Grogan 0eb155a0e7 Bug 1624760 [wpt PR 22431] - [FlexNG] Implement transferred size suggestion, a=testonly
Automatic update from web-platform-tests
[FlexNG] Implement transferred size suggestion

Aspect-ratio items with min-main:auto and a definite cross size use
cross size * ratio as an input to the min-main:auto algorithm. FlexNG
previously ignored that part of the spec.

<!--
content size suggestion is 300px.
specified size suggestion is 100px.
transferred size suggestion is 50px, but that is ignored because there is a
specified size. The ignoring is from the spec text that says,
(capitalization added):
In general, the content-based minimum size of a flex item is the smaller of
its content size suggestion and its specified size suggestion. However, if
the box has an aspect ratio AND NO specified size, its content-based
minimum size is the smaller of its content size suggestion and its
transferred size suggestion.
So here the content-based minimum size is min(300, 100) = 100.
