If you pass classes in the form attributes, they will be rendered in double quotes, breaking the styling.
Conversely, I need to pass the class without quotes (class=foobar instead of class="foobar"). However, this breaks the styling in the previous version of mautic (4.4), which is still in use.

How can we reproduce this issue?

Step 1: pass a class with quotes like class="foobar" into the form attributes
Step 2: Check the output with the developer-tools
