[ Navigation screen ] Improve auto focus to make "go to" consistent for nested blocks

[draganescu]

Incoming once #22996 is merged we need to remove the selection using a call in this form:

await selectEditorBlock( null );

This is required because Block List immediately applies focus when isSelected changes. Given we need to prevent this maybe there is a way to improve how preventing it works and update the effect here:

gutenberg/packages/block-editor/src/components/block-list/block-wrapper.js

Lines 136 to 140 in e1a6a78

	useEffect( () => {
	if ( ! isMultiSelecting && ! isNavigationMode && isSelected ) {
	focusTabbable();
	}
	}, [ isSelected, isMultiSelecting, isNavigationMode ] );

It's not clear yet if it is really a problem. It may be that the same problem here is causing this:

@draganescu Was this fixed by #25322? I'll close it, but feel free to reopen.
