cell navigation/edit on focus breaks custom template

[WorkMAE]

I am using a custom dataList template I created which I am referencing in this issue:
#6755

However I found another issue. When I turn on cell navigation and edit on focus, it no longer functions properly. The drop down works initially, but you cannot type anything into the cell. Also if you click on it once something is selected, you cannot change or delete the contents. This is obviously a problem because the dataList should be able to be edited and changed. Functionality works when I remove edit on focus and cell navigation but the initial problem I talked about in issue 6755 is still there.
