StackOverflow Exception when trying to access ApplicationMenu while RibbonMenu is minimized

[DavieMakesGames]

First, create a Fluent:Ribbon.Menu item with a nested Fluent:ApplicationMenu item.
Then, create a Fluent:RibbonTabItem underneath.

Steps to Reproduce:

1. Collapse the ribbon.
2. Click on one of the RibbonTabItems (to show the ribbon).
3. Click on the Fluent Application Menu.

I created an event that monitors the mouse click on the Fluent Application Menu and the stack overflow exception happens before this event it triggered.

Can reproduce and will have a look.
