Looking at the functionality of
keep_pressed_outside in BaseButton
Note: This property only affects the button's visual appearance.
Signals will be emitted at the same moment regardless of this
This seems incorrect in my opinion. I think it should also stop signals as the name implies. Unless it's renamed
keep_visually_pressed_outside or something but I have seen a few other peoples having issues with keeping buttons not pressed when you press and drag away from the button and release. They have to do weird logic to satisfy that logic.
Let me know what you think.
