Description

Twig macro variables don't work when imported from a separate file, and a fallback is provided using a null coalescing operator. However, macros defined within the same template are callable.

Steps to reproduce

1. Create a macro in a helper.twig file.

{% macro foo(param) %}
  {{ param }}
{% endmacro %}

2. Call this macro in a different file.

{% from 'helper.twig' import foo %}
{{ foo('bar') ?? '' }}

Expected behaviour

Output string.

Actual behaviour

Error: Call to a member function hasMacro() on null.

When called within the same file, it works fine

{% macro foo(param) %}
  {{ param }}
{% endmacro %}

{{ _self.foo('bar') ?? '' }}
{# Output: bar #}
