As requested by Kenneth in #714, a short snippet illustrating issues we have been seeing with rows disappearing from a tree grid after a store notify.

I can't tell whether this is a dup of #714 so I'll leave it up to you to decide. Problem encountered with dgrid v0.3.13 and dojo 1.9.3. dgrid v0.3.11 does not seem to have this issue.

Thanks in advance,
Thomas
