Apparent bug in btn action, quark open publishing theme

Hi there

I’ve been tweaking my site and noticed that when I click on buttons such as the RSS feed button, i.e. the css class “btn” the button does not deactivate after activation.

This means that you have to actively click away on some whitespace on the page in order to deactivate the button.

This feels like UX issue and for the sake of completeness I’d love to solve it,

Many many thanks to anyone who has a quick solution,
all the best
