Description Dirk Schulze 2014-01-26 05:20:57 PST 
background-position doesn't support "center 50% top".

This is also the case for basic shapes that use the same syntax.
Comment 1 Dirk Schulze 2014-01-26 05:21:58 PST 
Ditto for center "50px center 50%".

Sorry, meant "center 50px center 50%".
Comment 3 Dirk Schulze 2014-01-26 05:27:41 PST 
"top 50px", "center 50% top 50%" don't work either

Offsets from center are not allowed as part of the background position syntax. See:

That's the point. Closing the bug as invalid.
