bug#36037: Setting Koutliner view spec to <|benl1> and then back to <|ben> does not restore outline view

[Bodertz]

The manual "(hyperbole)Links" says this:

"[...] The form, '<@ 2b=06 |ben>' additionally sets the view spec of the
current outline back to the default value, with a blank line between
each cell and the whole outline visible."

However, setting a view spec to <|ben> after setting it to <|benl1> does
not make the whole outline visible. Is this an issue with the
documentation, a bug in Koutliner, or am I just misunderstanding
something?
