Previously, the parent CSS stylesheet, owner node and owner CSS rule properties were not unset when removing a sheet from a StyleSheetList. This change moves the methods for adding and removing sheets to and from a StyleSheetList, directly into the StyleSheetList class and ensures they are called as required by the CSSOM specification.
