This regex doesn't match these headers (is the leading ?: a typo?) so
there is no warning.

(?: ... ) is in Perl non-capturing grouping

From perlre(1)

  "(?:pattern)"
  "(?imsx-imsx:pattern)"
       This is for clustering, not capturing; it groups subexpressions
       like "()", but doesn't make backreferences as "()" does.

So it is not a bug, and it definitely should match... unless implicit
variable $_ (the default input and pattern-searching space) got
mangled.  It would be better to use explicit form:

   $variable =~ /pattern/
