Not working with Gin theme

FYI: The patch does not work for the recent stable release of Gin (v3).

Hi, here a new patch for Gin v3.

Edit.

This fixed things for me with Gin v4. Thanks!

On a related note, I noticed that if I ended up with with a dropbutton containing only one item then the styling was slightly broken. I raised a ticket on the Gin issue queue 🐛 Single dropbutton missing styling Active about it, in case it's useful for anyone.
