Pivot Table - Null reference when navigating to a different page

[Lee Stevens]

After the PivotView initially appears, before the data is rendered the user can navigate away by changing page or to a different tab.

In this scenario a null reference exception can be thrown, I have only been able to replicate it on PivotViews so far. Other controls such as grid and calendar seem fine.

Call stack:
[2021-05-11T10:22:26.145Z] Error: System.NullReferenceException: Object reference not set to an instance of an object.
