Virtualization Not Working as Expected After Removing Preselected Value and Scrolling Down in Popup

Description:
When a MultiSelect has values set during OnInitialized and the Clear "X" is clicked without opening the dropdown list, virtualization does not load beyond the first 30 options. However, if the list is opened before clearing, virtualization works as expected.


Sample: Sample


Replication Steps:

  1. Run the sample.
  2. Clear the preselected value.
  3. Open the dropdown and scroll down. Notice the issue—empty spaces are added.


Expected Behavior:
After removing the preselected value and opening the dropdown, virtualization should function correctly.


Actual Behavior:
After removing the preselected value and opening the dropdown, virtualization does not work as expected, resulting in empty spaces.
