Seems we are relying on Gtk+ for this so it works only if you press ctrl while clicking.

Selection mode should be single-click

Pretend the MODIFY_SELECTION modifier is pressed
(fake a Ctrl-pressed for example) to allow simple-click selection.

I wonder if this is really GNOME HIG compliant, but gnome-documents
seems to also do simple-click selection in collection view,
although it seems to use a different selection mechanism..

If it works, sure. :) Possible typo in commit log btw: "simple-click" -> "single-click"?
