Validator incorrectly reports validity for case of illegal escaped whitespace before property value

Test case checked using direct input mode, grammar CSS2 selected:

Test case :

	element {color:\ red; }

I believe that the above is illegal, if my reading of CSS 2.1 and CSS 2 is
correct, yet the validator reports no error.

Reasoning: the escaped space should be treated as _part of_ an _identifier_,
not as a normal whitespace separator. See the productions for "ident" in
CSS2 section D.2; CSS 2 only permits escapes within "ident"/"name", "string"
and "url".

So the property value should be an identifier " red", which is not a valid
value for the color property.
