DOMPurify: SAFE_FOR_TEMPLATES bypass - template expressions survive sanitization inside <template> content when using DOM output modes

Summary When DOMPurify is configured with both SAFEFORTEMPLATES: true and RETURNDOM: true or INPLACE: true, an attacker can inject template expressions, such as $evil, evil, or , that survive the sanitization pass inside element content. This bypasses the explicit purpose of SAFEFORTEMPLATES, whi...
