Subject: [PATCH] Don't show selected tree item when using multiple selection

This is appropriate for single selection, where the selected item is
also always the focused one, but not in the multiple selection case.

And wxMSW native version already behaves like this, so this makes the
generic one consistent with it.

Closes #18691.
