Confusing background for select boxes and config popups

[igorsantos07]

Think fast: what's being shown in the third row when configuring this Entities card?

Yep, that's a single option on the auto-complete of the 4th row's select, rendering in a way I wasn't really able to notice it there, unless I was looking at the screen while it changed.

I guess select boxes should have a different background, so they don't camouflage with the window's background?
