This is not a bug, according to my reading of the CLHS:

“If prototype is not supplied, then if the number is already a float, it is returned; otherwise, a float is returned that is mathematically equal to number but is a single float.”

Here, the prototype is not supplied, and the number is a float, so it is returned.
