Project Settings Test Height and Width should be an Editor Setting

The test size and with should be a function of the machine you are working on, not the project. They should be in the Editor settings alongside the test window placement. I assume they were not moved there at the time for some reason. But I think we should track this issue so that we can get to it one day in the future.

I guess the Game Window Placement section in the Editor Settings should be used for this. We already have Force Maximized and Force Fullscreen options available there.
