521333 - setting binding property to bad url and then unsetting it leaves things in a very different state

Status: RESOLVED DUPLICATE of bug 119078

(Core :: XBL, defect)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

My CSS transitions per-property mochitest currently tests that it's not missing tests for any properties on which transitions are supported by checking for transitioning behavior on other properties using the values in property_database.js, pairwise.  For -moz-binding, these values are currently 'none' and 'url(foo.xml)'.

However, if I run this test on the '-moz-binding' property, it causes a decent number of the rest of the tests to fail.  I haven't yet simplified it down to figure out what the problem is, but it seems pretty bad that setting and then unsetting a property can get things into such a different state.

To test this, simply remove the check:
      // FIXME: THIS SHOULD REALLY NOT BE NEEDED!
      prop != "-moz-binding") {
