Subject: \K in lookaround might become permitted in the future

It was disallowed because:

- it was breaking things (GH #14638)

- at the time, no-one had the tuits and knowledge to select non-buggy
  semantics and implement them.

(cherry picked from commit 55afc78396d86da97ab07c25295b00c9a300f081)
