mypyc: Any subclass of BytesIO will always generate an exception when instantiated

Bug Report

Any subclass of BytesIO will always generate the following exception when instantiated:
BufferError: Existing exports of data: object cannot be re-sized

To Reproduce

1. Run TestSubclassingBytesIO.py and notice it prints two instances (one of BytesIO and the other of SubBytesIO)
2. Using mypyc compile the 4 line file: SubclassingBytesIO.py
3. Then again run the tiny TestSubclassingBytesIO.py
4. The run will crash with the mentioned exception.

TestSubclassingBytesIO.zip

Expected Behavior
Running TestSubclassingBytesIO.py after compiling with mypyc should work just like running it before compiling. It should print:
<_io.BytesIO object at 0x0000026903075BC0>
<SubclassingBytesIO.SubBytesIO object at 0x00000269030A0630>

Actual Behavior
<_io.BytesIO object at 0x00000238D1D95BC0>
Traceback (most recent call last):
File "c:\Projects\mypycbug\TestSubclassingBytesIO.py", line 7, in
x = SubBytesIO()
^^^^^^^^^^^^
BufferError: Existing exports of data: object cannot be re-sized

Your Environment

• Mypy version used: 1.5.1
• Mypy command-line flags: None
• Mypy configuration options from mypy.ini (and other config files): None
• Python version used: 3.11.4

Inizia estraendo TestSubclassingBytesIO.zip ed eseguendo TestSubclassingBytesIO.py prima e dopo aver compilato SubclassingBytesIO.py con mypyc. Confronta i percorsi di istanziazione di BytesIO e SubBytesIO; il lavoro è completato quando lo script compilato stampa entrambe le istanze senza generare BufferError.
