uBO button options not visible from under menu button

[neekt]

I just started using the development version 1.13.11rc0 with Firefox 55.0.3 on macOS Sierra 10.12.6. This is a relatively minor issue, but when the uBO button is accessed from under the menu button, most of the extension options and settings are cut off and inaccessible:

If the uBO button is moved to the toolbar, it works properly:

This occurs using default uBO settings and filters.

Thanks for your work on this.

Very oddly looking result. :) It seems as if the functionality itself is working and the expanded widget works too, from the second image but may assume a different width through the menu button..
