Spanner right-hand text may disappear when padded

[Rutger Hofman]

Good afternoon list,

I have been noticing the following bug for a long time. If a TextSpanner 
bound-details.right.text is set, the text may disappear if it is right 
after a line break, and if it runs into some other markup-ish stuff. I 
am not sure whether this may also happen if bound-details.right.padding 
is *not* specified; but quite often, I need to pad the TextSpanner right 
to keep it at the same height as the following text. Try the attachment 
with right.padding = #0 to see what I mean: the right.text is pushed 
under the following markup.

This happens with the vanilla TextSpanner, and also with David 
Nalesnik's spanner-id TextSpanner.

A workaround can be found by inserting \breaks or \noBreaks, but that is 
an unappealing hack, and not maintenance-friendly.

Is there a 'good' workaround, or a 'good' way to let the TextSpanner 
behave in the way I want?
