Advanced Lookup Window Does Not Load Additional Data When Scrolling Down

What's happening?

When using the advanced lookup window for a Lookup field, additional data does not load upon scrolling down. Users experience this issue on different browsers, including Chrome and Edge.

Reason:

The out-of-box (OOB) control used for the lookup field does not load all data at once. It only loads a portion of the data, causing issues when users attempt to scroll down to load more data.

Resolution:

This is by design.
