Bug: Cannot set property isTrusted of #<Event> [canary] #1077
Description
On latest canary, I get the error:
TypeError: Cannot set property isTrusted of #<Event> which has only a getter
at Function.assign (<anonymous>)
at assign (http://localhost:7357/assets/vendor.js:38987:19)
at buildBasicEvent (http://localhost:7357/assets/test-support.js:4449:27)
at fireEvent (http://localhost:7357/assets/test-support.js:4429:15)
at http://localhost:7357/assets/test-support.js:4271:30
When running tests.
I would suspect this is because on latest canary assign from @ember/polyfills just re-exports Object.assign and this implementation somehow breaks here:
I will look into it to see if I can find the issue.
