I did now.

j-l-c-u-p seemed to be the only mechanism working reliably.  In my
f-l-fontify-region-function I tried to set the f-l-multiline and
j-l-defer-multiline properties on the region in question which had no
effect.  Setting the fontified property to nil in addition made it
work now.  I'm a bit short of time at the moment but will look at this
in more detail during the next days.
