Not sure what those failures about, from the logs it doesn't look like any tests or linter rules are actually failing?

@camjackson - I will take a look at this PR.

I am currently looking at a fix for #318 and I want to wrap that before I look at this, I assume there could be some overlap.

Thanks for approving and merging, @sriv and @zabil! When can we expect to see a new version of the extension published with this change?
