mailto-Links in RTE will not get rendered in frontend
Creating an email link with the RTE, the link is stored like <a href="mailto:email@example.com">Mail me</a> in the database.
The output in the frontend is like <a>firstname.lastname@example.org</a>. All allowed classes and attributes will be shown in fe, but not the href with the encrypted or blank mailto.
I think it's related to the latest security issue ac8f1fc3ac.
This bug occurs in version 9.5.29 and 10.4.19.
