Download ZIP button doesn't work

[tad-lispy]

Clicking the Download ZIP button in the Share tab gives the following error in the console:

editor-cf10984….js?vsn=d:1 Uncaught (in promise) TypeError: n is not a constructor
    at editor-cf10984….js?vsn=d:1
    at <anonymous>

Tested in Chromium and Firefox on OSX.

Thanks for reporting! I've got a fix for this locally, should be in the next release.

It works in Chromium now, but not in Firefox. Interestingly there is no exception (even a caught one). Something is happening when clicking the button - two chunks of JS are downloaded, but then nothing happens. I was trying to dig deeper, but it's not easy with minified and splitted code.
