MultiSelect with virtualization and tagMode: single deselects items when too many items are selected.
For convenience, attached is a small video demonstrating the behavior.
Note: So far I was unable to reproduce the issue in a Dojo example when trying to replicate the configuration from the project.
At some point, the dropdown popup will scroll up, and some items that have been selected, will be deselected. Also, the single tag for the selected items will disappear.
The component should not be deselecting items, should not scroll up and the tag should not disappear.
