Selected items disappearing

[Lee]

I have a kendo ui jquery multiselect with virtualization and sorting enabled. My issue is that for some reason, when a user selects 5 items from various parts of the list, closes the list, and then reopens the list twice, on the second time, there are only 4 items selected. Sometimes this will happen a third time where only 3 items are left. It is not completely consistent. I have a Dojo showing this: https://dojo.telerik.com/@dojolee/abUcAQag

I suspect something is either wrong with my sort function or valueMapper function but I cannot figure it out.

1. Select Stores 1, 25, 10, 30, 5 from the list
2. Close the dropdown list
3. Observe it says 5 items selected
4. Open the dropdown list
5. Observe 5 items are at the top of the list and selected but it is not the 5 correct ones.
6. Close the list
7. Open the list
8. Observe a different 5 items are not selected

I made a second, simpler, dojo here that has a similar issue: https://dojo.telerik.com/@dojolee/iJirimEh
