Dropdowns doesn't return consisetnt results while filtering a virtualized data

[mbechev]

Describe the bug
Dropdowns return different data when filtering the collection by the same character. The issue appears only when virtualization is enabled.

Notice the number of records returned when filtering by 's' in non-virtualized data (correct behavior).

correct-data.mov

When enabling virtualization, the returned data when filtering by 's' is different. The scrollbar doesn't appear.
