Single mouse click on root element of call hierarchy to jump to code line where "Call hierarchy" was requested from

If you ask for a call hierarchy via the context menu on a method call of bar(),
e.g. foo.bar()
you get the call hierarchy of bar().

Single clicking on "Incoming" or "Outcoming" gets you to the definition of "bar()".
Sinlgle clicking on subelments of Incoming or Outgoing get you to the defintions of the clicked method.
All very nice.

But there doesn't seemt to be a way to get back to the line foo.bar() where we started the journey.
How about single click on the root element to get back to the start of the journey?
At the moment clicking on the root element doesn't seem to have any effect.
