On Windows, if I create a QMenu and add enough QActions to it such that the number of QActions cannot fit within the height of the screen when the menu is displayed, the menu is supposed to get extra columns as necessary to display all of the actions.

I know this worked correctly in previous versions of Qt--probably 4.8.5, though I no longer have copy of 4.8.5 available on my machine to test.
The code in the attached experiment is simply:
