Do you mean a situation like this?

\score {
  <<
    { s1*3 \break s1*5 }
    { R1*8^"foo!foo!" }

  \layout {
    \compressFullBarRests

Ah!  Thanks a lot, that set me back on track.
>From my tests it seems that there is no need to reset X-parent of
MMRtexts, MMRnumbers and PercentRepeatCounters in this place - if we
let them continue to be what they were set to using previous patch
(i.e.  MMRs/PercentRepeat), everything seems to be fine.  What do you
think about it?  (a draft patch is attached - my tests say that it
doesn't change anything in regtests).
