Matrix scrolling updates go stale

[Robert Leach]

I had a TreeView jar running while I went to lunch. When I came back and started scrolling around, I noted that the matrix was not scrolling, so I started a screen recording:

It looks like zooming re-triggers the updates.

I'm not sure how to reproduce this issue. It's possible this might have been caused by something innocuous. I'll see if I run into the issue again.

Until it proves to be recurrent, I think we can assume this was a fluke.
