Build ID: 20180326160923
Steps to reproduce:
I did an instanceof test on an ErrorEvent emitted by XMLHttpRequest.onerror
See attached file on how to reproduce.
Actual results:
"error instanceof ErrorEvent" yields false. error.__proto__ gives me "ProgressEvent"
Expected results:
I expect "error instanceof ErrorEvent" to be true, as well as error.__proto__ to be "ErrorEvent".
