The correct title of this issue was not support NAMED attribute of details element
Joomla 6 is using the very latest version of TinyMCE and I have double checked with their official demo and that does not support the NAMED attribute. So there is nothing that can be done here until TinyMCE supports it.
But the GOOD news is that you can use it in Joomla by setting the TinyMCE plugin to use Joomla filters and not the tinymce filters
