The reason is that by using run selected on a single coded step, we don't get the automatic RefreshDomTree that is called during normal quick execution or in the case where there is a recorded step executing.

Note that in the case where only one coded step exists or the first step is coded step you still have to call RefreshDomTree in the beginning of the step. In other cases the problem is fixed and fix will be included in the service pack.
