LibWeb: Don't verify that a dimension unit isn't whitespace

Browse source 
Raw whitespace is not allowed inside a name, but escaped whitespace is,
for example `\9`, which is the tab character.

This stops yakzz.com from crashing the Browser, since it was using `\9`
in various places as a hack to only apply those properties to IE8/9.
