Buttons in header don't animate

With nav-bar animations it appears that only the title animates. The buttons just appear on the right or left during the animation. I did see a recent commit around the animation flickering but don’t know if it affected this. I just want to know if it is possible for the buttons to be part of the slide in animations or not.

They currently just stay in place with only the Title animating. Feel free to open a feature request on Github.
