Hi,
Are these two supposed to be equivalent?
@supports (not (foo: bar)) { }
@supports (not(foo: bar)) { }
heycam says[1] that not( is tokenized into a FUNCTION and thus
general_enclosed will match instead of supports_negation.
supports_negation's grammar has S* rather than S (I think it was S in an
earlier version?), suggesting that one should be able to omit the space.
To me, this smells like a spec bug. If the space is supposed to be
optional, it should parse into supports_negation when the space is absent.
If not, the grammar for supports_negation should say S instead of S*.
