Short description of error
I can't pan to the side more than this with the camera on the viewport. I wanted to have the cube in the center of the viewport but blender just doesn't pan anymore.
HOWEVER! if I change the ratio of the 3D editor, it works (up to a limit), it is a workaround, but a weird one!
Exact steps for others to reproduce the error
Open the file and try to pan to have the cube on the center of the viewport without exiting camera view:
This happens with this kind of resolution settings and the camera > sensor fit > set to Vertical (that I need in my project).
