Crash on showing too many elements

[anavgar]

I have a TreeDataGrid with a hierarchical structure. After expanding and collapsing several nodes I get an exception on the method 'RecycleElementsAfter'.

On RealizedStackElements.cs:

On TreeDataGridPresenterBase.cs:

Sreenshot of the Call Stack:

Steps to reproduce:

1. Open the hierarchical TreeDataGrid
2. Open all the possible nodes
   Then the crash will happen

Same issue on my side, but for me it happens when collapsing/expanding quickly multiple times. Have you maybe found a quick workaround @anavgar ?

Still happens on Release 11.1.1, just in case someone is interested.
