Hello,

I found an issue causing hover labels to overlap each other.

It can look quite bad in some cases:

Here is a codepen to reproduce it

I think it is has been introduced in 2.19.0, probably in this PR: #6442
You can see in the discussion @alexcjohnson noticing it, but it seems it has not been actually fixed in the end.
