ListView throws a IllegalStateException IllegalStateException #3455

Closed mattleibow closed 2 years ago

mattleibow commented 2 years ago

Description

This can be observed in the Essentials sample which uses a ListView. The page loads fine, but when the keyboard opens and the ListView is resized, the cell throws an exception. Switching to CollectionView does not throw and displays correctly.

Java.Lang.IllegalStateException: 'The specified child already has a parent. You must call removeView() on the child's parent first.'
