Circuit text diagram broken for a circuit involving both **0.5 and classical conditioning

[ikd-sci]

Description of the issue

Circuit text diagram broken for a circuit involving both **0.5 and classical conditioning on the previous measure.

How to reproduce the issue

The following code:

import cirq
q = cirq.NamedQubit('q')
circuit = cirq.Circuit(cirq.measure(q, key='m'), (cirq.X**0.5).on(q).with_classical_controls('m'))
circuit

Outputs:

q: ───M───X───────
      ║   ║
m: ═══@═══^^0.5═══

The expected ASCII representation should have been something like:

q: ───M───X^0.5───
      ║   ║
m: ═══@═══^═══════
