[Android] TouchBehavior prevents keyboard Tab navigation to next element - fix

[kubaflo]

Description of Change

e.Handled = false; is essential here because it preserves native focus navigation. Without it, your behavior unintentionally blocks keyboard input from reaching other controls or triggering system logic.

This subtle line prevents your TouchBehavior from hijacking the keyboard navigation experience — especially important on Android where keyboard interactions are more commonly used with physical keyboards or accessibility tools.

Pull Request Overview

This PR updates the Android touch behavior to preserve native keyboard focus navigation by explicitly not marking key events as handled.

• Added e.Handled = false; in OnKeyPressed to prevent hijacking keyboard input.
• Ensures other controls and system logic continue receiving key events on Android.

• Add a unit or integration test to verify that OnKeyPressed leaves e.Handled as false and that keyboard navigation remains functional after this change.
