TreeDataGrid is flickering when using a binding to a task with fallback value

[CodeDevAM]

Describe the bug

When a TreeDataGrid uses a TemplateColumn with a binding to a Task that returns a string the display is flickering when the underlaying Collection has a reset event.

In comparison a DataGrid view does not show such an issue.

There is no flickering if the TreeDataGrid is noch bound to a Task.

To Reproduce

Please see atteched example.

Expected behavior

I would expect no flickerung if there is no reason because of the actual execution time of the task. I would expect to get a similar visual experience that the DataGrid offers.
