Tree Macro: "openTo" not working on child nodes

Hello,
I would like to mark an item in the list with the parameter "openTo", but this only works in the top hierarchy (e.g. tomato) and not in the deep level hierarchies (e.g. baked beans).

I hope it can be solved.  

{{tree openTo='j1_1_anchor'}}
* Food
** Tomato
** Corn
** Baked beans
*** Beans
*** Onions
*** Ketchup
* Vehicles
** Car
** Bus
{{/tree}}

openTo='j1_1_anchor' does work

openTo='j1_2_anchor' does not work
