Event target

Hello,

nice little library !!

Is there a way to handle components that have a `phx-target` set?

```
 <.input
        type="search"
        id={@id <> "-input"}
        name="search_phrase"
        value={@search_phrase}
        phx-target={@myself}
        phx-change="search"
      />
```

An `assert_handle_event(view, "search")` does not work in this case....
