Wildcard import from express errors out

[cpsievert]

from shiny.express import *

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/cpsievert/github/py-shiny/shiny/express/__init__.py", line 46, in __getattr__
    return _get_current_session().input  # pyright: ignore
AttributeError: 'NoneType' object has no attribute 'input'

I'm not able to reproduce this. Here's a screenshot:

When it does the UI rendering pass, get_current_session() should return a MockSession object. For example, with this app:

from shiny.express import *

print(session)
print(input)
"Hello"

it prints the following to the console:

<shiny.express._mock_session.MockSession object at 0x102010f90>
<shiny.session._session.Inputs object at 0x1020110d0>

Update: I am able to reproduce this by running it at the console.
