This test verifies that we don't create anonymous grid items around
runs of inline content that are _purely_ whitespace.
The test uses "white-space: pre", to try to tempt us into honoring
that whitespace. (but we should resist that temptation).
The test also uses 'justify-content: space-around' to be sure we can
tell whether anonymous grid items are being created around the whitespace
