Error from docs: TypeError: Error is not a constructor

[cfjedimaster]

I tried the example shown in the docs for img.webc:

<script webc:type="js" webc:root>
if(!alt) {
	throw new Error("oh no you didn't");
}
`<img src="${src}" alt="${alt}">`;
</script>

Using latest Eleventy, latest WebC plugin, and I get:

The error goes away when alt is used of course, but the "right" error isn't being displayed to console.
