Thanks @mattharrison for the report.

I just tried and it seems to be working fine:

Would you be able to try in a private window, just to make sure it's not a cache issue?

Could this be related to #1335? We've had the same experience before where people who had been running an older versions got crashing pyodide kernel due to out of sync service worker.

0.2.3 works fine here as well, and these issues have been solved with clearing cache / similar.
