Subject: [PATCH] Don't increment node revision twice when attaching shadow
 root to element (#37865)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`Node::dirty` already increments the version. `Node::rev_version`
traverses all ancestors, so it can end up being fairly expensive.

Testing: I'm not sure about WPT coverage but I think this change is
trivial enough to merge without tests.
