Tracer Model P1.5 - when playing movie (if we have not created a login session) the app prompts for login, but the dialog does not appear

[pullmonkey]

1. refresh page to lose session
2. do not hover over a dot (this will prompt you for login and create a session)
3. play a movie with the controls, if available, otherwise, use grid.plots[0].movie.play();

You'll see a logger saying "show the prompt to the user", but no dialog.
This is the exact same code that is leveraged with image point hovering.

FSM said he'd take a look.

This is fixed now, the login object had to be refactored a bit
