[REG 4.6.2 -> 4.7.0] QML Profiler does not show extended statistics

1. Show the QML Profiler's Statistics view.
2. Right click into the view and select "Extended Event Statistics" from the context menu.
   Nothing happens. It doesn't seem to matter whether data was recorded before or not.

Extended statistics should be shown. In Creator 4.6.2, this seems to work correctly.
