Fix for #162

[tomnez]

Added this to dev since we're closing in on the v2.11.0 branch, I figure it can be a part of that release rather than go through a release cycle for this fix and then another one a couple days later after v2.11.0.

Let me know if anyone thinks I should repurpose this to go straight to master for a quick bugfix release instead.

How about adding a test for this? 🤔

Also thinking that theoretically we should release this independent of the Polaris 2.11.0 update so we don't force users to update just for a small bugfix... but then again I don't know if we currently have any users 😅

I think we can likely follow Ember suite and port this to the next 1.x+ version if anybody needs it...no biggie

[vladucu]

but yeah, a test would be nice

@vladucu added a test and resolved conflicts, will merge once it passes 🕺
