Reviewed by Darin Adler.
Add a fast path for notifyAttributeChanged() when called from
parserSetAttributes().
When called from parserSetAttributes(), we know that the Element is not
connected to the document and has no parent so a lot of work in
notifyAttributeChanged()
can be avoided.
This results in a 0.36-0.49% progression on Speedometer 3 (depending on
hardware) on macOS.
