is it an waste for PresShell::NotifyReflowObservers() to be called three time to open one html page?
hello, when I debug mozilla to open html page,
I noticed that PresShell::NotifyReflowObservers() to be called three times to open one html page.
I think maybe it is an waste of time.
I print call stack here.
I think at least the second call could be removed.
