Current behavior ag-grid with Filter options does not pass 508. The Filter fields do not get read by JAWS or NVDA

Expected behavior Expect the Filter fields to behave like ordinary input fields: JAWS should announce the name of each field as it gets focus.

Minimal reproduction of the problem with instructions add Filter to any ag-grid. Run JAWS of NVDA. Header cols are announced correctly but the Filter fields are not

What is the motivation / use case for changing the behavior? Our application must be 508 compliant
