When inlines nest deeply it's better to include them in the dirty chain (like layout does) just so we don't exhibit O(n^2) containingBlock() crawl-up behavior.

Moving all JavaScriptGlue bugs to JavaScriptCore. The JavaScriptGlue framework itself is long gone. And most of the more recent bugs put in this component were put there by people who thought this was for some other aspect of “JavaScript glue” and have nothing to do with the actual original reason for the existence of this component, which was an OS-X-only framework named JavaScriptGlue.
