Cannot change the date/time range in the Database's Session dashboard (4319199)

It is not possible to retrieve historical data in the Database's Session panel as the date/time range drop-downs are grayed out. This happens for both Oracle and SQL Server cartridges.

Steps to Reproduce:

1. Select Dashboards | Databases from the Navigation Panel.
2. Click on the "Go to Home Page" button right next to the instance name.
3. For SQL Server database: click SQL Activity | Sessions.
For Oracle database: click Activity | Sessions.
4. Click on "time range" at the top of the screen.

Actual results:
The 'From' and 'To' drop-downs are grayed out.

The Session screen is an RMI screen – on demand output screen. It shows what is happening just now hence the time range is not relevant on this screen.
