Using macros throws Uncaught TypeError: $ctor$$3_template$$3$$ is not a constructor

Here is how is use macros:
Note that panel/test.twig.js is included in the page as well. i'm guessing that there is something with how i use it. any suggestion ?

{% macro test(a1) %}
    {% include 'panel/test.twig' %}
{% endmacro %}
{% import _self as macros %}
{{ macros.test(a1)}}

Also when i remove {% import _self as macros %}, it no longer throws error but the macro also won't work and is ignored by compiler

{% import _self as macros %} cause twigjs to generate context["macros"] = this.env_.createTemplate(this); so it seems that using macros in the same template is not supported yet. I move the macro to a different template and imported it to work around it.
Also it seems that generally including a template inside a macro also does not work
