makemessages ignores {% trans %} block

[Eroica]

Hi,

I'm afraid I must be doing something wrong, but with the following setup, I cannot get makemessages to parse anything in {% trans %}...{% enddtrans %} blocks:

pyproject.toml:

[tool.poetry.dependencies]
python = "^3.11"
Django = "^5.0.6"
django-jinja = "^2.11.0"

settings.py:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'newstyle_gettext': True,
            "extensions": DEFAULT_EXTENSIONS + [
            ],
        },
    },
]

Then a sample template file in /subapp/templates/subapp/index.jinja:

{{ _("This works") }}

{% trans %}This gets ignored{% endtrans %}

{% blocktrans %}This also works{% endblocktrans %}

I then run poetry run python manage.py makemessages -l en -e html,txt,py,jinja which produces this .po file:

# SOME DESCRIPTIVE TITLE.

# This file is distributed under the same license as the PACKAGE package.

msgid ""
msgstr ""

"Language-Team: LANGUAGE <[email protected]>\n"

"Content-Transfer-Encoding: 8bit\n"
"Plural-Forms: nplurals=2; plural=(n != 1);\n"

#: .\subapp\templates\subapp\index.jinja:1
msgid "This works"
msgstr ""

#: .\subapp\templates\subapp\index.jinja:5
msgid "This also works"
msgstr ""

My problem is that I would like to use {% trans %}... for more complex strings, and I cannot use blocktrans because then Jinja complains about an unknown tag. Any idea what could be wrong? If required, I'll upload a whole sample project.
