Example on how to use ActionStyle.ToggleButton

Question

I know that a ribbon action has a Style property which exposes ActionStyle.ToggleButton but I can't find any examples in the GitHub repo (Sdl-Community) of how this is used. 
 From trial-and-error I can see that there's a Checked property which does hold the state, but the ribbon element doesn't toggle like I would expect it to - it offers no visual indication of state. 
 Should it offer any indication of state or am I expecting too much? I expected it to exhibit some sort of depressed or raised appearance.

You set the style in the constructor like this: 
 public MyAction()
{
 base.Style = ActionStyle.ToggleButton;
} 
 and then inspect/modify its state using 
 base.Checked 
 The visual indication is a slightly tainted background, hardly visible on small buttons like on the QAT.

Just tried to switch the icon on a Checked state change and it works. 
 
protected override void Execute() 
{ 
	Icon = base.Checked ? PluginResources.MyCheckedIcon : PluginResources.MyNormalIcon; 
 
	// ... 
}
