If a SimpleButton has a hover state, the hover state remains visible after the button is clicked. It will only disappear after the user moves the cursor off the button. This does not mimic the Flash behavior of a SimpleButton which is after the button is clicked, the upstate is automatically displayed.
I’m guessing that this behavior is true for all build targets, not just HTML5.
I think that in OpenFL the visual behavior of a SimpleButton should be the same as in Flash.
In the meantime, does anyone know how to force a Simple Button to display its upstate?
