Test has been imported in LayoutTests/ietestcenter/css3/grid
This test is invalid per the latest specification as a negative <integer> for grid-{column|row} has a definite meaning.
Sorry, this was posted to the wrong bug. '0' is still invalid for grid-{column|row} and is a bug in our implementation.
Created attachment 196044 [details] Proposed trivial change: Don't accept '0' as a valid grid position and fix the test to enable CSS Grid Layout under testRunner.

All reviewed patches have been landed. Closing bug.
Removed the test from mac too in http://trac.webkit.org/changeset/147445. This was forgotten in the original change and the Mac buildbots were listing the test as passing.
