* This tests for transitions generated on the -webkit-text-fill-color property.
* This property has an initial value of 'currentcolor' so by triggering a
* transition on the 'color' property we also--at least at the point when
* this test was written--trigger a transition on the -webkit-text-fill-color
* property (that behavior may change in bug 1260543).
*
* However, before beginning the test we disable -webkit-text-fill-color by
* setting layout.css.prefixes.webkit to false. This code tests that we don't
* end up triggering a transition on the (disabled) property in that case.
