IGNORE ILLEGAL CSS SHORTHAND VALUES FOR PROPERTIES

[LeinardoSmith]

If illegal values such as "clip" are applied along with other values in the shorthand format property such as background, the whole series of values is not applied instead of just the clip value being ignored.

For example:

$test.css("background", "white no-repeat content-box clip");

When accessing the background property:

console.log($test.css("background"));

Returns:

null

Should Return:

white no-repeat content-box

Retrieval of shorthand CSS properties (e.g., margin, background, border), although functional with some browsers, is not guaranteed.
