Description Javier Fernandez 2015-10-07 13:18:32 PDT 
It seems that the computed value and CSSOM serialization for several grid shorthands is not right.

For detailed list and example to reproduce the issue, check this thread on www-style:
https://lists.w3.org/Archives/Public/www-style/2015Jul/0242.html

The following W3C test can be used to check the cases that are failing in Chrome:

Note that the expected behavior is not 100% confirmed yet:

https://wpt.fyi/results/css/css-grid/grid-layout-properties.html?label=master&label=experimental&product=chrome&product=firefox&product=webkitgtk&aligned&q=webkitgtk%3Afail

shows we only fail two tests that any other browser passes, and in both those cases we match Chrome's behaviour.
