The draft <http://dev.w3.org/csswg/css3-background/#the-background-size> does
say “If only one value is given the second is assumed to be ‘auto’”, but this
sort of behavior doesn’t make much sense to me, especially given the behavior
of background-repeat and the 4-value (top-right-bottom-left) properties, where
missing values are filled in with specified values.

If the spec isn’t going to change, we will need to fix this bug, but we will
also have to undo the aliasing of -webkit-background-size to background-size
and have the former maintain the current parsing. We also need to decide what
to do about -webkit-mask-size.
