I'm seeing other areas using IEditorCommandsContext which possibly do not extract the context correctly so we need to check all these cases. Also, it's possible that the wrong multiselect context is used (list vs tabs) for example when focus is on open editors view but action is run on tabs. Maybe IEditorCommandsContext should include the source of the action so we do not have to figure it out by checking focus?

I would think a good outcome is if we had 1 method for commands to use and the others variants staying private. That ensures we have 1 way of unwrapping context for all consumers. Maybe certain behaviour should be configurable via options if we need specific behaviour, but then it becomes very explicit.
