Hi, Tim, Thanks for the tip! I hadn't thought of that as a direct workaround of sorts, but that does open the doors for another way to get it to work, I think :)
It's not-so-much accessing the data that's the problem with this bug (which I probably should have explained), but rather some of the fields of the itemRenderer--specifically, the depth field. I guess I could, instead of relying on that field, just traverse the tree upwards from the selectedItem and calculate the depth manually in the "bug" case.
