Indeed it seems that this is the case, but i don't see any sense in it.
It is obvious that MultiMeasureRest itself should be a spanner, but
its number is just a text, an item with a fixed width.  Why should it
be a spanner?
I've traced this code back to commit 0d239922, which introduces
separate grob for MMRnumbers, and i found no explanation why it should
be a spanner.
I've tried changing them to be Items, but all i got was a segfault (my
attempt attached).
Suggestions?
