When this happens, what happens next? If you stop the scroll and start scrolling again, does it work? Or do you have to do something more complicated to get things working again?
On rare occasion that's going to happen -- when Composer updates its model of the document, that resets the scroll map used for synchronized scrolling, forcing a recalculation. But the scrolling should pick right back up after the map is reset -- that recalculation should be fast (it's the same delay that happens before scrolling can start to begin with).
I tweaked one thing for the next release (34) but it shouldn't make a difference. Everywhere I can find that could have temporarily disabled scrolling has been removed.
