Test: enable a spec testing CSS whitespace preserving in Edge 17

mgol · web-flow · commit 81d829b3573e · 2018-06-18T18:48:15.000+02:00
In Edge 14-16 setting a style property to a whitespace-only value resets it to the default, forcing us to skip a relevant CSS test in Edge. Now that Edge 17 has fixed the issue we can re-enable this test there. Ref gh-3204 Closes gh-4101
