Hi there! We are really interested in this improvement😊. In our case, the list may contain up to 9,000 items, and the combobox interactions are quite slow. Idea: Apply a concept of infinite scrolling, but still maintain filtering functionality (very important for large lists).
Related to the virtualization effort in https://github.com/Esri/calcite-design-system/issues/7384
Actual Behavior
combobox has significant lag in response time when 3,200 combobox-items are added and nested.
Also, displays with more lag when it prevents the containing parent panel from opening. The panels themselves load in slowly when they contain the combobox with many combobox-items. Occurs whether or not the icon property of calcite-combobox-item is populated, for instance:

Expected Behavior
Improved performance and response time when large amounts of combobox-items are present, in particular where over 100, or hundreds/thousands of elements are present.
