CompressMMRests issue

[Denis Penard]

Dear all,

I am now engraving Manhattan Symphony in Lilypond.

I encouter an issue with CompressMMRests. Here is the code. I just take 
some bars not the whole score.

After the third \partial (red one below), I attempt to get a 8 
compressed rests bars but the eight bars are unfolded.

If I remove the two partial before, it works.

If I add a bar with some notes, it works.

It looks like a bug isnt'it?

Best regards

Denis
