Selected visual state

[Toomas75]

In our MAUI application, we are encountering a challenge with maintaining consistent visual states for UI elements. Here's a simplified explanation:

When a parent element is set to a "disabled" state, it overrides the states of its child elements( property value propagation. For example, if a parent is disabled and a child element is set to "selected," the parent's "disabled" state takes precedence, and the child appears disabled as well.

When the parent element's state changes back to "enabled," the child element should return to its "selected" state. However, the current behavior resets the child element to its normal state, not recognizing its previous "selected" state.

This issue makes it difficult to consistently manage visual states in our application, as changes to parent elements inadvertently affect the states of child elements in unintended ways. (CollectionView...)

Despite numerous issues being reported, they end up in the backlog without resolution. This delays our ability to provide a seamless user experience.
