It seems that requesting reflow multiple times to an <iframe> causes odd race condition.

The test requests reflow to a child document which the listener listens to
when expected event gets received as a message. However, the message listener
is set twice for listening same events on <html> and <div>. Therefore,
the request occurs twice, and that assumes that the reflow happens before
the next task of a setTimeout call.
This patch makes the order stabler.
- Request reflow only when the the last expected event is received
- Remove the message listeners when the reflow request is performed in the child
Severity: N/A → S3
