Since installing wpForo Advanced Attachments, formatting is stripped when saving a forum reply/post — the editor toolbar itself displays fine, the problem happens specifically on save. It fixed a separate inline-images issue but caused this new one.
Browser console shows this error in the reply/editor section: [Violation] Permissions policy violation: unload is not allowed in this document.
