Description

Steps to reproduce:
1. Create a TabNavigator
2. Programatically add a Tab which contains a Panel containing many form items (ComboBox, HBox, TextArea, CheckBox, etc.)
3. Programatically remove the tab
3. Notice memory usage and response time slowly rise

Actual Results:
Over time, memory usage and response time rises

Expected Results:
A linear memory usage / response time

Workaround (if any):
Current workaround is to code child.removeAllChildren(); from within any method that "closes / removes" the tab from the TabNavigator
