Frozen columns - overlap on hover

[poison4o]

Description of the bug

If you have a frozen column(s), and you have some other column(s) under the frozen, on hover the row, the value of the back column(s) overlap the value of the frozen column(s). This is also tested with the latest version of vaadin 14.8.14

Expected behavior

The value of the column(s) that is under the frozen column(s) shouldn`t be visible

Minimal reproducible example

When you have a frozen column, and you want to scroll(horizontal scroll), the other columns will go under the frozen column(s), which is fine but when you just hover the row, you will see that the value that is under frozen column(s) is showing.

This is not reproducable with the example from the documentation at least: https://vaadin.com/docs/v14/ds/components/grid/#columns. Can you please provide a minimal reproducable code example to test this?

Also note that the latest version for Vaadin 14 is 14.8.14.

A related issue for editable cells in GridPro was fixed recently: vaadin/web-components#3753, however the fix was not ported to 14. The provided example should clarify if the issue is about Grid or GridPro.

You can see the uploaded video, so currently i`m using 14.8.6, but i have mentioned 14.8.14 because i switched to it just to check whether i`ll have the same behavior, and i have it. So i`m using Grid. The cells are not editable.

@poison4o Please provide a code example that reproduces the issue, from the video it's not clear what you are doing that could cause the issue. As I mentioned above, for a simple case like the one demonstrated in the docs, the issue does not occur, so there must be something specific to how you setup the grid.

So the problem is on my side, i found out, that there is a custom css which is causing the problem, so the issue is fixed
