Short description of error
Even if "allow negative frames" is on in the animation preferences, you cant move the start frame to negative frames
Exact steps for others to reproduce the error
go to preferences > animation
tick on "allow negative frames"
go to the start frame and drag it negatively.
nothing happens.
