In the handler path it checks if the platformView.Background is of type BorderDrawable, in that case there is a BorderRadius > 0 check before applying the given borderradius. So 0 doesn't work.

If you were to set Cornerradius to 1, you would get a very slight radius but it works. That is a workaround that could be good enough.
