{% parent %} not working as expected in Administration

PHP Version

8.0

Shopware Version

6.4.7.0

Expected behaviour

Start custom block 1
Block two!
End custom block 1

Actual behaviour

Start custom block 1
Start block 1
Block two!
End block 1
End custom block 1

How to reproduce

In PHP twig, we have the {{ parent() }} notation which will call the block of the parent page you're extending. On the twig.js, it does not work the same. It works great on level 1, but not any deeper than that. {% parent %} always calls the extended block of the first level.

a.html.twig

{% block test_level_one %}
    Start block 1
    {% block test_level_two %}
        Block two!
    {% endblock %}
    End block 1
{% endblock %}

b.html.twig

{% extends 'a.html.twig' %}

{% block test_level_one %}
    Start custom block 1
    {% block test_level_two %}
        {% parent %}
    {% endblock %}
    End custom block 1
{% endblock %}

For the record, I was first creating an issue in the twig.js repo, but it seems that the {% parent %} tag is shopware-specific, and not from Twig.js itself?

Slots using Extension SDK is the future. So we would not invest time to change that 😅
