Bug - Menu: Drilldown examples' height not set as intended

[thatblindgeye]

Describe the problem
The drilldown examples (except for "initially drilled in" example) don't have their height set as intended in the setHeight method within the example code.

How do you reproduce the problem?
Select a menu item with drilldown in the drilldown example, notice that the height shrinks and causes the menu to no longer be visible.
