A good starter for this issue might be to implement the activate such that it doesn't back out on null selection (just leave out the select statement). The consistent support of navigation might be done in a follow-up issue.

Seeing you on a similar path :) Just to summarize, with null selectionModel

- appropriate keys on the focused row starts the edit with null selection model
- focus navigation is left for a future issue 

two suggestions: 

- we might want a test to capture the start edit, f.i. on SPACE
- file an issue covering the focus navigation to not forget?
