Extend modular.html.twig in child Quark theme


I’m trying to add some code in modular.html.twig - {% block body %} - in my child theme.
But when I add the modular.html.twig with {% extends ‘modular.html.twig’ %} it results in:
Fatal error : Allowed memory size of 536870912 bytes exhausted…

For what I could gather, this results in a loop hence the memory exhausted.

Is it possible to extend a template from parent to child theme? Or do I have to copy the full template to the child theme?


Is it safe to say that there is no way to extend the template directly from parent theme?
For now i copied modular.html.twig to child, but this undermines the inheritence principle, I think.

Still searching…
