Theorem bdceqir 15406

Description: A class equal to a bounded one is bounded. Stated with a commuted (compared with bdceqi 15405) equality in the hypothesis, to work better with definitions ( B is the definiendum that one wants to prove bounded; see comment of bd0r 15387). (Contributed by BJ, 3-Oct-2019.)
