Nested macro call with caller() misses context

[LeaVerou]

Sorry for the poor description, I couldn’t figure out a better one.

Testcase:

{% macro page() %}
<section class="page">
	{{ caller() | safe }}
</section>
{% endmacro %}

{% macro test_page() %}
{% set page_content = 'foobar' %}
{% call page() -%}
	{{ page_content | safe }}
{%- endcall %}
{% endmacro %}

{{ test_page() | safe }}

Should produce:

<section class="page">
	foobar
</section>

Instead produces:

<section class="page">
	
</section>

Jinja2 gets it right btw.

To add to @LeaVerou's comment, if we move {% set page_content = 'foobar' %} inside the call block, it produces the expected result:

{% macro page() %}
  <section class="page">
    {{ caller() | safe }}
  </section>
{% endmacro %}

{% macro test_page() %}
  {% call page() -%}
	{% set page_content = 'foobar' %}
	{{ page_content | safe }}
  {%- endcall %}
{% endmacro %}

{{ test_page() | safe }}
