Cannot be used on angle bracket components below Ember 3.8

<MyComponent {{on "click" this.doSomething}} />

Fails with Element modifiers are not allowed in components

I realised this addon doesn’t have -polyfill in the name, is that why it doesn’t work on the lower versions?

[amk221]

I see now that this is due to missing behaviour to do with splattributes, not the on modifier.

Hey @amk221! Thanks for making this explicit.

If you want, you can submit a PR to add this to Compatibility. If you got no time for it, that's also fine. I'll get to it myself then.

Yeah, I really wish we could polyfill that behavior but it is quite hard.
