Workaround for the inability to access the full context inside a block inside a StreamField in Wagtail

foo.py

{% for block in self.body %}
  <section class="{{ block.block_type }}">
    {% if block.block_type == 'fooblock' %}
      {% get_foo block.value request %}
    {% else %}
      {{ block}}
    {% endif %}
  </section>
{% endfor %}

@register.inclusion_tag('home/tags/foo.html', takes_context=True)
def get_foo(context, block, request):
    return {
        'block': block,
        'request': context['request'],
    }
    
# foo.html
<section>
  {{ request }}
