Cannot read property 'userAgent' of undefined on FastBoot

Hi there!

I encountered a problem using the power-select with Ember FastBoot.

There was an error running your app in fastboot. More info about the error:
 TypeError: Cannot read property 'userAgent' of undefined

I suspect that the problem is coming from https://github.com/cibernox/ember-power-select/blob/master/addon/components/power-select-multiple/trigger.js#L7.

Hey @cibernox, any ideas how can I fix this problem? I'm open to work fixing this problem, I just need some guidance.

[cibernox]

Hey. Sorry, I forgot to answer to this in the very moment and then it felt into oblivion. I think that it shouldn't be hard to fix. Probably is this line:

ember-power-select/addon/components/power-select-multiple/trigger.js

Line 14 in 67e1c63

const ua = self.window ? self.window.navigator.userAgent : '';

Basically the component should not attempt to access the navigator if it's not running in an browser.
