False positive for translation string

[monachilada]

{{ _self._attr(attr, sep|default(' ')) }} is falsely showing up in my translation list as a string to translate.

Full line from source code is as follows:

{% if attrs|length %}
    {% if attrs is iterable %}
        {% for a,attr in attrs %} {{ a }}="{{ _self._attr(attr, sep|default(' ')) }}"{% endfor %}
    {% else %} 
        {{ assume|default('title') }}="{{ attrs }}"
    {% endif %}
{% endif %}

Thanks, this and one other issue have to be resolved by me creating a regex pattern that I'm working on, but is a though one.
