Twig variables get escaped inside some HTML-tag attributes in header & footer E-Mail templates

[Dead-Man-Walker]

PHP Version

8.1

Shopware Version

6.5.3.0

Expected behaviour

Twig variables don't get escaped after saving the header and footer E-Mail template and thus get interpreted as twig variables instead of being rendered as a string.

Actual behaviour

Curly braces of twig variables get escaped inside some HTML-tag attributes in header & footer E-Mail templates and thus do not get interpreted as twig variables but instead being rendered as a string.

How to reproduce

1. Create a new header and footer E-Mail template
2. Add the following HTML code to the HTML mail header and HTML mail footer textarea: <img src="{{ salesChannel }}" alt="{{ salesChannel }}" /> <a href="{{ salesChannel }}" class="{{ salesChannel }}">{{ salesChannel }}</a>
3. Save

The HTML in both textareas will have been converted to the following: <img src="%7B%7B%20salesChannel%20%7D%7D" alt="{{ salesChannel }}" /> <a href="%7B%7B%20salesChannel%20%7D%7D" class="{{ salesChannel }}">{{ salesChannel }}</a>
