  3. It's green.
  4. Do the same in FF29.

Correct, it seems that with FF29 started to drop exception in case of catastrophic backtracking. This issue is already fixed in master (with #11754), and will be present in 4.4.1.

Please check if this test still fails against current master.

Passes on my FF29 on master.

Actually, I should've closed it as a DUP of #11754.
