Comment #6 on issue 2655 by [email protected]: TextSpanner disappears after linebreak

I think it would make sense to collect at least the example starting this issue report and the example for issue 654 into a regtest, possibly even a few more. If a problem requires several changes in order to home in on one solution, having a regtest for it would seem rather prudent.
