Christian Biesinger ffecd1d287 Bug 1541689 [wpt PR 16156] - [css-flexbox] Correctly calculate min-height with justify-content, a=testonly
Automatic update from web-platform-tests
[css-flexbox] Correctly calculate min-height with justify-content

Spacing added by justification is not meaninfully part of the
intrinsic block size of an item; remove it.

This is especially problematic with percentage sizes, because
with height: 100% and justify-content: flex-end we would
position any flex items at the end and calculate a minimum
size based on the 100%, even though we ought to ignore percentages.
