#### Summary
Seeing an issue with websocket connections keepalive (ping/pong)
#### Steps to reproduce
Send a ping FRAME with arbitrary data payload.
#### Expected behavior
Server should not try and decode the data payload in the ping
#### Observed behavior
Serve reports an error

Here is the `ping()` frame sent from the client:
```auto
DEBUG:websockets.protocol:client > Frame(fin=True, opcode=9, data=b'\xd0\xe2M\xd4', rsv1=False, rsv2=False, rsv3=False)
client ! timed out waiting for pong
```
By the way this was reproduced using the latest Team edition version 5.33.1

Confirmed that the issue is not present in 5.32.1
Here is the log from the working `ping/pong` using that version
```auto
client > Frame(fin=True, opcode=9, data=b'\xa27\xd0\x08', rsv1=False, rsv2=False, rsv3=False)
DEBUG:websockets.protocol:client > Frame(fin=True, opcode=9, data=b'\xa27\xd0\x08', rsv1=False, rsv2=False, rsv3=False)
client - event = data_received(<6 bytes>)
DEBUG:websockets.protocol:client - event = data_received(<6 bytes>)
client < Frame(fin=True, opcode=10, data=b'\xa27\xd0\x08', rsv1=False, rsv2=False, rsv3=False)
DEBUG:websockets.protocol:client < Frame(fin=True, opcode=10, data=b'\xa27\xd0\x08', rsv1=False, rsv2=False, rsv3=False)
client - received solicited pong: a237d008
DEBUG:websockets.protocol:client - received solicited pong: a237d008
