Eric Willigers 62873a3536 Bug 1573658 [wpt PR 18407] - CSS: Shortest serialization for gap shorthand, a=testonly
Automatic update from web-platform-tests
CSS: Shortest serialization for gap shorthand

gap is <'row-gap'> <'column-gap'>?
https://drafts.csswg.org/css-align-3/#propdef-gap

If row-gap and column-gap are the same, we serialize
only a single value, consistent with Firefox and
the shortest representation principle.
