filterPlaceholder parameter of filterParams has no effect on Date filter

According to the docs, the filterPlaceholder parameter of filterParams can be assigned to Date filters. I have tried to provide them as various string formats, but it has no effect on the placeholder text, even when the browserDatePicker property is set to False.

I suspect this is not an issue with dash-ag-grid but with ag-grid itself: https://github.com/ag-grid/ag-grid/issues?q=label%3AAG-3735+is%3Aclosed. As the issue has been in their backlog for quite some time, I think it would be necessary to remove this parameter from the docs. If there is a way to override the locale (since the date format is locale dependent for the Date selector), could you please provide an example?
