Pyodide compatibility?

Would you be willing to accept patches to make this package work with Pyodide? Before version 1.2.0, it worked with Pyodide but from version 1.2.0 it fails with

RuntimeError: Runner.run() cannot be called from a running event loop

I'm not sure if this is better fixed in Pyodide or pytest-asyncio, probably it's better to fix in Pyodide. I think the cause of the issue is that Pyodide's WebLoop event loop doesn't handle lifecycle events. For instance, stop() is a no op. This is because our event loop schedules events on the JavaScript event loop and we have no control over the JavaScript event loop. But perhaps we can fake lifecycle events well enough to satisfy pytest-asyncio's needs.

Anyways if there is any interest it would be nice to add Pyodide to pytest-asyncio's CI once we get this working.

Start by reproducing the RuntimeError with pytest-asyncio 1.2.0 under Pyodide, then inspect how Runner.run() interacts with Pyodide's WebLoop lifecycle methods, especially stop(). Determine whether the compatibility change belongs in Pyodide or pytest-asyncio. Done means the package works under Pyodide and Pyodide coverage can be added to CI.
