Allow tags in attributes

[Khartir]

Explain the problem

Currently the parser does not allow tags in attributes. Valid Twig-Code like <option {% if disabled %}disabled{% endif %}> is not possible.

Expected Behaviour

Allow valid tags in attributes.

This came up in the prettier-plugin: https://github.com/trivago/prettier-plugin-twig-melody/issues/37

Is there a reason for this limitation or this is simply something that has not been implemented yet?

We're currently getting hit by the same issue, it'd be great to know if there are plans to support this at some point :)

As another example, this is failing for us in our base template:

<meta name="description" content="{% block meta_description %}{% endblock %}">

Why would this cause a problem? It is most normal and most common thing in the twig files. How can twig formatter failing on this? Seriously?
