In Bevy 0.9, I am watching for Mouse5 or Mouse4 to be pressed using MouseButton::Other(32) and MouseButton::Other(64).

However, it only recognizes the input on the first press, and then proceeds to no longer recognize the input. Left click works fine.

The code I used in Bevy 0.9 to watch for mouse input follows:

fn watch_for_mouse_input(mouse: Res<Input<MouseButton>>) {
    if mouse.just_pressed(MouseButton::Other(64)) { println!("Detected input 'Mouse5'!"); }
    if mouse.just_pressed(MouseButton::Other(32)) { println!("Detected input 'Mouse4'!"); }
    if mouse.just_pressed(MouseButton::Left)      { println!("Detected input 'Left Click'!"); }
}

And the output in console (comparing when the input is recognized vs the MouseEventInput stream from Bevy) is attached in this screenshot:

Notice how after Mouse4 and Mouse5 being recognized once, subsequent presses are no longer recognized.

It seems that, when releasing mouse4 or mouse5, it is being recognized as MouseButton:Other(0) rather than 32 or 64, and so MouseButton::Other(32) and 64 are not being recognized as being released.

If I hold mouse4 (32), then hold mouse5 (64) at the same time, it says that MouseButton::Other(96) has been pressed. If I release mouse4, it says MouseButton::Other(64) has been released, and then the next time I press Mouse5, it is recognized one time.

My apologizes if this is not actually a winit issue; I'm not sure if this should be reported here or in the Bevy github somewhere.
