It took some time to find a solution to this, but finally, thanks to MCL, a Stack Overflow member from Germany, Folders Popup now open new Explorer windows with or without the left navigation pane, according to your Explorer Layout settings. In previous versions, Folders Popup always created new instances of the Explorer (using the Shift-middle mouse button) with left navigation pane opened, regardless of your choice in previous Explorer instances. This misbehavior is now over.

A user indicated that Folders Popup is particularly useful when you want to save screen real estate by turning the navigation pane off. To control this setting, open the Organize menu at the top left of the Explorer window and open the Layout sub-menu.
