Huh? Sure you can.

The engine's rules for combining greedy and non-greedy behavior might be
a bit different from Perl's, but that doesn't make it "limited". It
just means it has different idiosyncrasies from Perl's engine. I do not
accept the proposition that Perl's regexps are perfect and everybody
else's are wrong to the extent that they act differently from Perl's.

As for the specific behavior at hand, it does look like a bug from here,
but I don't have time to poke at it right now.
