What happened?

It seems that although you guys support pyscript.when with Micropython, it does not support passing a non-string element. For example:

from js import window
from pyscript import when

@when("popstate", window)
def on_popstate(event):
    pass

This results in an ImportError:

  File "pyscript/event_handling.py", line 27, in decorator
ImportError: no module named 'pyweb'

I took a look at the relevant file and it looks like there's a logic fork for non-string selectors on when, which isn't supported in Micropython.

The docs don't make that clear, however.

What browsers are you seeing the problem on? (if applicable)
