Transparent Button - Border when clicked?

When a button is transparent (back ground color and border color set to transparent) when you click it there's a border around the button. Like you click it and a colored border appears. Is this just to show a button was clicked or is there a way around it? if its part of Construct 2, just to show a button has been clicked, that's fine.

The border is probably used to indicate the button was clicked.
