Modifiers don't seem to work when applied to elements are ember components with `tagName=''`

Using modifiers on an element that is itself a classic Ember component (`@ember/component`) doesn't seem to work.
This poses difficulties because the developer now has to 'know' :godmode: what the
other component is.

This works great:

```hbs

This not so much (doesn't error, doesn't execute).

```hbs

```
