SubSection - selected though no sections selected or visible
I deselect and hide sections in .onInit.
If I deselect and hide all sections of a SubSection, the SubSection
is still shown and selected.
How can I hide the SubSection if all its sections are deselcted
and hidden?
If I don't hide the sections, the SubSection is deselcted (as it
should be).
I have attached a small script that demonstrates my problem.
