Momdo-san, could you check whether this issue is already fixed in stable or Nightly? Although we improve line segmenter rules by 1719535, before landing it, this seems to be already fixed.

Redirect a needinfo that is pending on an inactive user to the triage owner.
:jfkthame, since the bug has recent activity, could you have a look please?
For more information, please visit BugBot documentation.
