Could not import the json example into www.speedscope.app

I downloaded simple.speedscope.json and tried to import this into www.speedscope.app.

But this gives in Chromium (Firefox didn't work as well):

speedscope v1.16.0

Hi @mulle-nat! Thanks for the report -- I can reproduce, which is strange because there's a test that covers this file! https://github.com/jlfwong/speedscope/blob/de17f128d0ce9d2a696ac7772dec6393dc2888b4/src/lib/file-format.test.ts#L5

Will investigate next time I sit down to work on this code
