2. Click on the "Data Packs" button, select any of the experimental data packs that are available, and then hit the "Done" button.
3. Now hit the "Details" button and click on any element within the list using the mouse cursor in an attempt to select it.
4. Now try and select any element within the list using keyboard navigation and observe how you're able to do so.

Observed Behavior:

The said element cannot be selected via the mouse cursor but can be selected via keyboard navigation.

Expected Behavior:

The said element would be able to be selected via the mouse cursor.
