Stream Window is not rotated on port 81

[normvp]

I am finding that I can easily and properly rotate the image in browser using port 80, while I am configuring the ESP32_Cam_Webserver, however, The stream that I want to watch on port 81 is not rotated. I can flip back and forth between two open tabs for the ESP32-Cam and see correctly rotated on port 80 and ignoring the rotation setting on port 81. This puzzles me because I can temporarily see the rotated stream on port 80. Do I misunderstand what the steam should be capable of, or is there a bug with rotating the stream on port 81?
