This reproduces ionic-team/stencil#5016
We claim to support styleUrls, putting multiple stylesheets into a component,
but this doesn't work!
In this repro my-component has two stylesheets, one of which sets the
background to red. However, if you:
npm install
npm startYou will not see a red background. You can confirm that it's pulling in only
the first stylesheet by either switching the order of the filenames in
styleUrls or checking the style tag in the shadow root in the inspector.
