Description Andrea Iacovitti 2016-05-21 18:45:25 UTC 
Example:    {background: none left left red no-repeat;}
The declaration is invalid because it specifies two horizontal value for background-position (left left) then should be discarded. 

Reproducible: Always

Fix parsing background-position in shorthand declaration.
If two values are specified advance the value list pointer only if the entire property is valid.

Can you double-check that this change it doesn't break other valid CSS? For instance the test case given in Mozilla's developer notes for background-position breaks even after I revert my proposed changes to the CSS parser. See https://developer.mozilla.org/en-US/docs/Web/CSS/background-position, the output was working in previous KHTML commits.
Comment 4 Michael Pyne 2016-05-22 23:45:27 UTC 
Actually never mind. I'm not sure what seemed to break this but it's happening before your changes were merged in so I don't think it's that.
