In the console, a _ can be invisible due to collapsing with the border of the input field

I set prio high as it is so trivial, though very confusing if not fixed

This is a styling issue: In chrome, I do not see any _ in a one line property in the console, in firefox for me, only the third property (dunno why the third) is the _ invisibile

Think the input fields should get a bottom padding of at least 1
