Trying to change camera view in Minecraft Java Edition on Mac is not working.

Please see my screen recording using the keyboard viewer to show when F5 is pressed. To show this is not an "F-Key" issue on my Mac, the same approach is taken pressing F3, which pulls up the right F3 screen.

I am running Mac OS 10.15.4. I should update my Mac (10.15.7 is available) but I am lazy. Not sure if this is the issue but I doubt it.
