This is the stack trace. When user clicks "Sign in" the menu is synchronously updated and the action is recorded. Of course the view is destroyed immediately so the user doesn't see the new version.

CC+ Thomas as he also worked on the DICE user menu.

Don't update the profile chooser if it's to be closed.

Unnecessary update skews the metrics. Typical flow before the CL is
- The profile chooser shown.
- User clicks something.
- The profile chooser is being hidden.
- Some state changes and updates still existing bubble.
