Inconsistencies with 3D Touch and the scrub gesture when used inside Home screen folders
If you use 3D Touch to open the ‘Quick Actions’ menu on an icon in a Home screen folder, using the ‘scrub’ gesture to close that menu actually closes the folder. The ‘Quick Actions’ menu remains on screen and you have to use the scrub gesture again to close the menu.
Note that this only occurs if you activate the Quick Actions for an item and do not swipe around the screen to explore the Quick Actions. If you navigate to one of the available Quick Actions and perform the two-finger scrub, the gesture works as intended and you are placed back on the item’s icon inside the folder.
