Hi, that's correct. Because the layout needs to have a ripple on press, a background with the surface color is set.

@leticiarossi Thank you!
Maybe it can be helpful to state this behavior in the documentation? (Or maybe I missed it)
I have searched a lot to find where this background color comes from. ☺️

We've been updating our components documentation but haven't gotten to menus yet, will make sure to include that! The code itself can be found here.
