I can reproduce the behaviour. It seems this was introduced to support SGML's
syntax for <FOO/bar/ which is apparently a shortcut for <FOO>bar</FOO>. But I
don't understand why it tries to match a / if it's after a <. (I'm not very
familiar with SGML's quirks and special syntax.)
It seems the code in `sgml-slash' actually tried to deal with that case but in
the end still calls `sgml-slash-matching'. The following patch would fix that

Until then you could use (define-key sgml-mode-map "/" nil) as a workaround to
disable the matching in all cases.
btw. maybe `sgml-quick-keys' should be customizable.
