[MacCatalyst] Picker control Focused and Unfocused events does not trigger whether focusing manually or programmatically.

[TamilarasanSF4853]

Description

On macOS, the Picker control does not correctly update the focused and unfocused count when triggering .Focus() and .Unfocus(). The Focused and Unfocused event handlers execute, but the labels displaying the count do not reflect the expected updates. This issue occurs when interacting with the picker via buttons that programmatically call .Focus() and .Unfocus().

Note: While fixing this issue enable the mentioned UITest: Issue2339

Steps to Reproduce

1. Run the attached sample application on macOS. PickerIssue.zip
2. Click the "Click me to call .Focus on Picker" button.
3. Observe that the Picker Focused count label does not increment.
4. Click the "Click me to call .Unfocus on Picker" button.
5. Observe that the Picker Unfocused count label does not increment.
6. Click the "Click me to .Focus() picker, wait 2 seconds, and .Unfocus() picker" button.
7. Again, observe that the focused and unfocused count labels do not update.

Expected Behavior:

The Picker's Focused and Unfocused event handlers should update the respective count labels when triggered.
Clicking the focus and unfocus buttons should increment the displayed counts accordingly.

Actual Behavior:

The Picker's Focused and Unfocused event handlers execute but do not update the count labels.
The UI does not reflect the change when the picker gains or loses focus.
