Systemjs: Chaining cycle in promise with async execute

[dmail]

I'm using systemjs to have top level await in the browser.
However there is a promise cannot resolve with itself error, you can reproduce with a simple fiddle like this one: https://jsfiddle.net/9odyajcw/.

Is there a way to make it work ?

When you're inside the fiddle, open the browser console to see logs.
You should see 42 being logged and after that an error about promise cycle.

Thanks for the report! Will aim to take a look soon at the case and fix.

So this was a bug specifically with s.js, not found in system.js. I've fixed this up in https://github.com/systemjs/systemjs/commit/cc44badb9545182b1d121dd5c06f50ccd3079e23 - thanks so much for the clear replication.

Amazing thank you very much for the fast response and fix. That will help me to finish my project relying on your work on systemjs.
