Firefox | Fronzen columns

[ilmandone]

On FF 89 / FFD 90.0b7 frozen columns not working properly.

It seems a problem of z-index.
The issue is not present into header's cell.

Are you on the latest canary version? I can't reproduce the issue here.

Yes: last canary version .49 .

I found the origin of this issue.
It seems that only on FF if you apply a pseudo element on a cell at mouse hover the frozen feat glitch.

On FF

On Chrome

CSS code:

.rdg .rdg-row:hover .rdg-cell:after{
    content: "";
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    display: block;
    background-color:rgba(0,0,0,0.1);    

    pointer-events: none;
}

Add:

Same pseudo element on the row works fine.
