Comment 28 for bug 1164150

The buttons are entirely different in master. I've now got a + and a - icon next to each other - a huge waste of space on my screen - I dislike that change a lot, because I can no longer access the kerning and letter rotation settings (aside from a couple of preset values), and the keyboard shortcuts for those don't work, either, with a German keyboard, AND they cannot be set in the keyboard shortcuts list, so even the workaround for the workaround doesn't work.
Maybe those fold-in-fold-out animated toolbar content changes Jabier uses could be a solution here, too. Or a more useful dropdown, that allows to enter numbers. Or wrapping the toolbar, if needed.

I think V has been working on a 'small' gtk theme?...

Anyway, double-clicking on any of them just makes the number change twice, so *this* issue is fixed in master.

I think [1] is probably the correct commit.
