Shell Flyout appears in Release builds even when FlyoutBehavior="Disabled" (MacCatalyst)

[lettucrisp]

Description

On MacCatalyst, setting Shell.FlyoutBehavior to Disabled prevents the flyout as expected in Debug builds. However, in Release builds the flyout can still be revealed by dragging the Shell content area from left to right.

Steps to Reproduce

1. Create a new .NET MAUI
2. Set the app Shell’s FlyoutBehavior to Disabled.
3. Run the app in Release, and drag from the left edge of the content.
