The XML text is shown in "within delimiters" mode not after the very

Somehow emacs 26.2 took that error in stride, while it chokes emacs
26.3. But not a bug, I guess.
Unescaped greater-than is well-formed in XML. The only case where it MUST
be escaped is when representing a ]]> sequence inside a <!…[…[…]]>.
