Description Manuel Rego Casasnovas 2014-12-04 06:49:34 PST

There're not enough coverage for ::first-line in grids and flexboxes.
Mainly we're missing coverage when the pseudo-element is set on ancestors of the grid/flexbox checking that it's ignored.

We'd need to port the following patch from Blink and apply something similar to flexbox too:

This will be done once bug #138424 is fixed (similar issue related to ::first-letter) in order to have clear all the cases we want to test here.
