@gkalpak - thx
@topherfangio - is this a better fix than #9012 ?

[gkalpak]

@topherfangio, we were obviously working on this simultaneously 😄

So, this is essentially very similar to #9012. The main difference is that I split the test for different empty mdOptions into separate tests. This is a good idea anyway imo, because you are using the same scope ($rootScope) in all cases, which could result into one test's state affecting the subsequent tests.
_{(This one also avoids some unnecessary calls, but this is insignificant in the context of tests).}

[topherfangio]

That's not a bad idea. I think a merging of the two would be good? I like explicitly calling closeSelect() so that it's apparent to the user what we expect to happen.

[ThomasBurleson]

@topherfangio - can you merge this with latest from master (which already has 9012 merged).

[topherfangio]

@ThomasBurleson Will do; I'll shoot over a new PR in a bit.

Superseeded by #9041.
