This was caused by me in #515, and it can be worked around by setting a logo with setLogo(). I realize now we neglected to test the layout without setLogo() which causes the buttons to float to the top in the absence of one.

I will probably release a 1.1.1 version to fix this issue.

This has been fixed by 1.1.1
