Background visible above MenuBar/MenuItem

Hi. I have a component in which there are various TextFields and a MenuBar. This component is displayed in a div with multiples of the same component, arranged vertically:
Now, when the MenuBar is clicked, the dots of the MenuBar below appear over the MenuItems:

Thing is, there is no custom CSS that would affect this. Everything front-end wise looks correct. Has anyone ever come across that issue?

I can reproduce this, but only in Firefox. Does that match your experience?
