Fixes #611

I'm not sure, did the travis build failed due to my changes?

[StefanCodes]

I'm able to run the e2e tests locally and they all pass, but the Travis logs show that Protractor failing with an exception. I don't see how your changes could result in this error.

@Voles did you encounter anything like this when you were setting up the e2e tests?

[dangoodman]

@StefanCodes, thank you for response. Sadly @Voles did not please us with his comment.

Well, now travis build goes successfully. I've just forced it to re-run and it went ok. Not sure what has been changed. What I can say for sure is that the commit did not changed.

For now, is there any reason to not merge the commit?

[Voles]

Sorry for the late reply. The PR looks good, merged!

[dangoodman]

Thanks!

[Voles]

@dangoodman are you interested in helping us with further development of the component? :-)

[dangoodman]

Yep. I'm going to do a couple of drag-n-drop UX improvements. Hopefully you'll accept them. Or do you mean something else?

[Voles]

No, that would be perfect! Looking forward 👍
