Button with mixed state

It seems that since the commit introducing animation, switches show up incorrectly when they are activated before they are shown. See attached test.c and screen shot. The first button is activated and the second button is deactivated before the window is shown. The second one shows up correctly, the first one not.

The same problem will probably occur if you call set_active after showing it as well, no ?
