Revision d0d62244432d329aa22e9278d3e83184301c3e7f authored by Chris Nardi on 07 April 2018, 01:36:26 UTC, committed by Xidorn Quan on 07 April 2018, 02:05:46 UTC 
Update expected cssText for custom property serialization
 
See https://github.com/w3c/csswg-drafts/issues/2509#issuecomment-379152590 for the change to target9. Also remove the extra whitespace in target8 and target1 which causes these tests to fail in Chrome and Firefox.

Also remove testcase.propertyName from each test's name as this doesn't exist and just outputs undefined.
