Same issue here. I also tried to experiment with different z-index but hat no success.
Any update on this issue?

I checked out Firefox/Windows 10 and does not happen, maybe it's a Chrome quirk?

I am facing the issues on Windwos10 with Firefox.

True, I am able to reproduce it also maybe I did something wrong the last day :/

After some testing, I've found out that the problem has to do with relative-absolute positioning that is being used with tooltip, as this stack overflow answer points out: https://stackoverflow.com/a/611098/1842548

The problem is that changing this would introduce breaking changes, as a new element must be introduced, sadly.

If we were talking inside a framework context such as React, the library consumers would not notice it, but as is a css pure framework, the implications are... well rather complicated.

We should look for solving this anyway.
