• Qiskit Terra version: 0.23.3
• Python version: 3.9
• Operating system: Ubuntu 18.04.6

What is happening?

I construct a mcry gate with three qubits as control qubits, and one qubits as target qubits. When I bind parameters, it doesn't work.

How can we reproduce the issue?

from qiskit import QuantumCircuit, QuantumRegister, Aer
from qiskit.circuit import Parameter

qr = QuantumRegister(4)
qr_control = qr[:3]
qr_target = qr[3]

qc = QuantumCircuit(qr)
para = Parameter('input')
qc.mcry(para, qr_control, qr_target)
qc = qc.bind_parameters({para:1})
qc.draw('mpl')

What should happen?

the value 1 should be binded with 'input'，but it doesn't.

Any suggestions?
