Research direction

Reproduce the failure in the beta editor at https://python.microbit.org/v/beta using the attached mimic-19Sept20.zip file and the Load/Save “Or browse for a file” flow. Trace the file-loading entry point from the browser error shown in the report; done means the old file loads without the reported error.
