include only parser issue

[ghost]

As described in #453, this throws an error although it should work according to the Twig documentation : {% include "header.html" only %}

These work but are unintuitive: {% include "header.html"  only %} {% include "header.html" with {} only %}

Good luck...for some reason I can't get a simple include working...

@ScoutsOut we would need more details about your template and how you setup your env to help you.

I can confirm this is not working as expected: https://codepen.io/willrowe/pen/VwXeQQj.
