Vendor prefixed properties without a stable spec should not require the standard

[fryn]

"Vendor prefixed properties should also have the standard."

This should only be required for vendor fixed properties that developed into a stable spec. Otherwise, it defeats the entire point of vendor prefixes.

For example, it does not make sense to include user-focus when using -moz-user-focus, even though a W3C Working Draft exists. On the other hand, it does make sense to include transform as well as its vendor prefixed variants, despite the spec still in the Working Draft stage.
