Describe the bug / provide steps to reproduce it

I have dpi scaling on windows set to 150%, I just noticed that there's a line separator between the function fingerprint and the description in rustdoc hover popups (see attached video).
Scrolling by that tiny amount reveals the 1px separator that otherwise would be hidden
