Custom css code for sticky doesn't work since new update

[Kappa]

Hi there,
I'm running into a big issue since the new update.
Using a css code for having elements sticky to the bottom, which worked perfectly, stopped with the new update.

Very much appreciate any ideas how to solve this, since it's a core feature for the website I am building.

.sticky{
    position: sticky !important;
    top: 95vh !important;
    white-space: nowrap !important;
    overflow-y: visible !important;
    z-index: 99999 !important;
}
