inspector breaks for Glimmer Components containing {{link-to}}

Instructions to Reproduce

ember new -b @ember/octane-app-blueprint my-app
cd my-app
ember s
ember g component x-foo

Define the component as follows

app/components/x-foo.js (unaltered)

import Component from '@glimmer/component';

export default class XFooComponent extends Component {
}

app/templates/components/x-foo.hbs

{{link-to 'Go Home' 'index'}}

Finally… open the ember inspector, and select the “Components” tab. The error message below seems to be logged each time the tab is clicked (i.e., alternating back and forth between components and another tab will cause the error to be logged repeatedly)

Is it really the inspector?

The error goes away if the extension is removed, or if the “Components” inspector tab is never used

@mike-north thanks for the incredibly detailed issue here! Template only components and glimmer components do not currently work with inspector, I don’t think. We definitely will have to figure this out before Octane drops.

Should be fixed by #1088 in the next release.
