Vadim Zeitlin 73cab0bd4e Keep children of collapsed item selected in wxGenericTreeCtrl 
Collapsing a branch shouldn't deselect all the items under it in
multi-selection mode: this doesn't seem to be useful or otherwise make
sense and makes the generic version gratuitously incompatible with the
native MSW one.

Closes #10239.
