:first pseudo-selector conflicts with CSS paged media module's :first

[visnup]

webkit nightly r58385 [1] added support for css paged media, in particular the :left, :right, and :first pseudo-selectors. this means webkit won't throw an error when ":first" is encountered by querySelectorAll and instead returns an empty array [2]. this breaks any selectors using sizzle's :first pseudo-selector in the latest webkit nightlies.

I've filed another bug against webkit, hoping to get errors thrown (again) when :first is encountered outside of an @page rule context [3].

forgot how trac formatting works and can't edit the description now to make the footnote links clearer.
