System Text in middle of a bar needs to break MMRests at the start and end of that measure for all parts, so can display text.

In the attached score, there is System Text of "rit" in the middle of meas 2.

But the Horn part won't display that system text:

What would have been a 3-measure MMRest has been broken apart at start of meas 2 due to the presence of the system text "rit". But this is a pointless breakup, because the system text doesn't get displayed in the part since the entire measure is collapsed into the MMrest.
I say that any system text inside a middle of a measure should cause all parts to display that measure as a regular (non-MMRest) measure. Only measures before and after that measure containing system text should be allowed to be allowed to collapse. I consider this a bug.
I notice this behavior in 2.0.3, and 2.1.0 (23b060d), and 3.0-dev (bfebf95b6)
