  ### What happened?
  
  After the changes related to stdout/err and display, the antigravity example is broken. It currently fails with the following error:
  
  ```
  Traceback (most recent call last):
    File "/lib/python3.10/site-packages/_pyodide/_base.py", line 435, in eval_code
      .run(globals, locals)
    File "/lib/python3.10/site-packages/_pyodide/_base.py", line 304, in run
      coroutine = eval(self.code, globals, locals)
    File "<exec>", line 1, in <module>
    File "/home/pyodide/antigravity.py", line 44, in <module>
      _auto = Antigravity(append=True)
    File "/home/pyodide/antigravity.py", line 14, in __init__
      target = target or sys.stdout._out
  AttributeError: '_io.TextIOWrapper' object has no attribute '_out'
  ```
  
  This is due to the fact that we are not custom changing `sys.stdout` the same way.  
  
  It seems like the best option here would be to implement the right `_repr_` method but would love to hear @philippjfr on this
  
  **NOTE: ** goes without saying that we should add a test as well :)
