Fix the visual styling of the vertical timeline toolbar
Submitted by Jeff F.T.

The vertical "inline" toolbar on the right of the timeline doesn't look totally native. The path to the solution is in https://bugzilla.gnome.org/show_bug.cgi?id=738474
It is a bit unclear to me if it's still considered a gtk bug (as I always thought it to be) or us //Doing It Wrong//.
