After enabling forced portrait mode, I was playing around with the portrait mode lock screen and noticed that, immediately upon sliding to unlock in portrait mode, the task launcher button and clock briefly appear as they would if the desktop were in portrait mode (in the upper left). After a few tries, I was able to tap the task launcher button to open the task launcher immediately after unlocking and while the desktop was still in portrait orientation before rotating to landscape. It just takes a single tap with the right timing. Sign of whats possible or no?
