### Nested editable manual test * Put selection inside `foo bar baz` nested editable. Main editable and nested one should be focused (blue outline should be visible). * Change selection inside nested editable and see if `Model contents` change accordingly. * Click outside the editor. Outline from main editable and nested editable should be removed. * Check following scenario: * put selection inside nested editable: `foo bar baz{}`, * click outside the editor (outlines should be removed), * put selection at exact same place as before: `foo bar baz{}`, * both editables should be focused (blue outline should be visible).
