The current default setting for the new DataGrid is to only display a filter icon when hovering over the column header with an applied filter. In contrast, the previous version had the icon visible at all times.
For reference, you can view the Codesandbox example here.
Upon applying a filter, a new iconButtonContainer div is added with the following classes:
MuiDataGrid-iconButtonContainer css-ltf0zy-MuiDataGrid-iconButtonContainer
I am wondering if there is a way to change this behavior. Ideally, I would like the visibility of the icon to remain constant whenever that div is created by the library.
