Dialogs are added to the DOM by MagnoliaShellViewImpl.addModal() after they are created. The problem is that when the dialog is created, an ActiveTabChangedEvent is sent from the MagnoliaTabSheetConnector activeTab stateChangeHandler to the TabBarWidget to set the active tab label. But this event is sent before the TabBarWidget is initialised, resulting in no tab label being selected.

There must be a better route - ie RPC that would not be dependant on the timing of creation.

Concretely - this Timer delay should be removed.
