zone.js loaded by twice, by two separate sources

I built a JS widget using angular 2 that is embedded on other websites. One of the sites that the widget is embedded on has another script that loads zone.js. So when my script loads I get the error:

Error: Zone already loaded. at new g...

Is there a way to configure angular-cli (1.0.0-rc.0)/webpack to not load zone.js if it has previously been loaded?

I was able to solve this issue by ejecting the webpack config then namespacing my chunks via the jsonpFunction option.

To be honest I don't understand how this resolves the issue of zone.js being loaded twice- but it does.

Should the same be done for loading patches?
