1564984 - Green up and re-enable wpt css tests skipped on geckoview

Status: NEW

(Core :: CSS Parsing and Computation, task)

Description

[Maja Frydrychowicz :impossibus (was :maja_zf) (needinfo me)]

web-platform-tests have been running against GeckoView for a couple of months, and we've found that several tests in this component are unstable and need investigation.

Here is the state of disabled tests according to testing/web-platform/meta at revision 241af4dbb964

(Note that I split out the css-backgrounds tests into Bug 1564981.)
