Enabling "Use keyboard navigation" messes with NSTableView

I have an NSTableView where I use the 

tableView(tableView:shouldTypeSelectFor:withCurrentSearch:) -> Bool

delegate method to select certain lines with the SPACE key like this

func tableView(_ tableView: NSTableView,
               shouldTypeSelectFor event: NSEvent,
               withCurrentSearch searchString: String?) -> Bool {
    if event.charactersIgnoringModifiers == " " {
        // Perform action on currently selected row(s)
    }
    return false
}

That works fine, but when the setting in

Preferences > Keyboard > Shortcuts > "Use keyboard navigation to move focus between controls"

Is turned on, the table view loses focus entirely after hitting the SPACE key. If I check my responder chain afterwards, I can se that the focus moved back to the window.

Another sideeffect of turning this setting on is that if I have a check box (NSButton) in the selected table view cell, its action will be automatically called when hitting SPACE.

The setting explicitly states it only moves focus on TAB and SHIFT+TAB, not change how controls work.

Why does this happen? Can I disable this behavior at least partially for the table view of the app?

After almost losing my last hair here is what resolves it

  • Make sure all your cell subviews have refusesFirstResponder set to false

Now the table views first responder status is not lost.
