What worked in the end was (building off the idea that running the
mouse cursor over the buttons forced a relayout of the style):

this.actor.grab_key_focus();

In this case 'actor' was the St.Bin containing everything (but I think
doing this to each individual button or any of the parents would have
worked too).

Woohoo!
