Element helper always render a div.

My case:

This example does not work for me, it returns an exception

```handlebars
{{#let (element 'span') as |Tag|}}
hello world!
{{/let}}
```
```
'The `element` helper polyfill encountered an unexpected error. ' +
'Please report the issue at http://github.com/tildeio/ember-element-helper ' +
'with the usage and conditions that caused this error.'
```

myComponent.hbs (glimmer)
```handlebars
{{#let (component (-element 'span')) as |Tag|}}
I Want to be a span
{{/let}}
```
result:
```html

Should be
```html

I Want to be a span

```
