Can not check Event Stream in Chrome Network Panel when using polyfill

Hi,
I testing this polyfill in the chrome broswer, but i can not check the event stream in Network panel, when i switch to the native api, the event stream can be shown in the network panel. just like that:

We've also found this and due to other issues (as well as this) in the polyfill have had to revert to the native EventSource object so that we can monitor our event streams for troubleshooting.

Chrome will only show native EventSource in the network panel. The polyfill uses XMLHttpRequest or fetch.

How do you suggest we fix this issue?

@danwale @aslakhellesoy
Neither I read the source code, nor familiar with EventSource, so I have not any suggestion with this issue. In my opinion, switch to use native API when detecting in google chrome maybe is perfect solution in my application code.

Thanks for your answer
