On https://ryex.github.io/ic10emu/ , in the javascript console:

And (presumably relatedly), the editor isn't showing up at all

Ah, looks like it's because I'm using firefox: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Iterator/forEach#browser_compatibility

Sorry for not mentioning that in the initial report

Thanks for pointing that out, I was using the map iterator completely wrong and should have tested Firefox too. I went for the solution of using forEach directly on the Map instead of on the keys iter
