corejs causes conflict with can-connect

[tracer99]

We have an issue with our DoneJS project where IE11 routing doesn't work under some conditions. Based on recomendation by one of your devs on gitter, we include corejs in our main app file.

import "core-js/client/core";

This has been running fine in production for months.

We didn't try to use Models until recently, but it appears that just importing can-connect causes the app to crash

import superMap from 'can-connect/can/super-map/';

See this revision of an example of this in action

The error output is TypeError: Cannot read property 'push' of undefined which I was not able to successfully debug.

Depending on what page is loaded when, this error will either take down the server or throw an error in the client.

@tracer99 Do you have the gitter conversation? Do you know why the dev recommended it or which developer it was?

Have you tried this with a 1.X version of can-connect?

Thanks!

@justinbmeyer It's a DoneJS project, so I'm assuming that trying to upgrade can-connect in isolation will not go well?

@tracer99 any updates on this? I'm trying to clean up old issues. Thanks!
