Bug 645491 part 2. Speed up changes to id attributes on pages with lots of id selectors. r=dbaron The basic idea is to only match against id selectors which might matter by keeping track of them in a hashtable instead of a flat list. We still need to use a flat list for possibly-negated id selectors, unfortunately. 2011-04-13 02:57:48 +00:00			`<!-- This test needs to be in quirks mode -->`
