Should check element, and return false if is null initially.

Issue Details:
The user has defined an implicit style for the BackgroundColor property of a Grid, with the selected state value set to green. However, when the IsEnabled property of the CollectionView's parent Grid is changed from false to true immediately on the button click, the background color of the currently selected item (which is also a Grid) is lost.
Root Cause:
This happens because changing the IsEnabled property triggers the ChangeVisualState() method in the base VisualElement class. As a result, the visual state transitions to "Normal", overriding the previously applied "Selected" state and its associated background color.
Description of Change:
To address the issue, a selection check has been added to ensure that the "Normal" state is not forced when the element is currently in the "Selected" state. This change preserves the visual appearance of selected items by preventing the "Selected" state from being overridden during IsEnabled property changes.
Tested the behavior in the following platforms.
