The root cause seems to be confusing m flag of Ruby and JavaScript.
Actually m flag of Ruby only changes the semantics of . and does not change ^ or $.
Equivalent flag in JavaScript is s.

Yes @takaram, I was also mistaken about this in the first version of the post. Later I edited it to clarify. But I wasn't aware of the JS s flag. #2610 fixes this issue by transpiling the regexps (but still needs some work due to performance impact). As of now, . is transpiled to [\s\S] if m flag is present. I foresee an issue with things like Regexp.union if we chose to depend on the flags.
