Pointer release not observed on Mac if pointer press opened a modal window

[TomEdwardsEnscape]

Create this button in a window:

var button = new Button
{
    Content = "Click me",
    ClickMode = ClickMode.Press,
    Margin = new(100),
};
button.Click += delegate { new Window().ShowDialog(this); };

1. Click the button on Mac.
2. Close the window
3. Click outside the button

At step 2, you will see that the button is still in its "pressed" state.

At step 3, the Click event handler will execute even though you didn't click on the button. This is because the button is still capturing the mouse pointer.

Expected behavior

The button registers pointer release and behaves in the same way as it does on Windows.
