Data Grid column filtered indication not shown any more

I did an update from version 2023.12 to 2024.12 and now I cannot see any more if a column filter is set or not.
If filtering of a column is enabled the filter icon is always shown and though I cannot see any more if a column is filtered or not. Because the filters are persistent I have to check every single column when no data is shown.
Here a screenshot with the good old one above and the new underneath.

AGGrid provides a mechanism to add custom styles based on whether a filter is set or not. See docs:

So you could either hide the filter icon when ag-header-cell-filtered is not applied, or as in their example, add a little dot to indicate an active filter.

As an example, to hide the icon when no filter is set:

.ag-header-cell:not(.ag-header-cell-filtered) .ag-header-icon {
    display: none;
}
