Unexpected undefined in Virtualizer.scrollToIndex

[damienrobson-sage]

Describe the bug

scrollToIndex throws an error if the list of items in a drop-down is emptied after an item has been selected. From the looks of things, the measurements are being reset to 0 when calculating the location to jump to, which results in an empty array being used to find the index.

Your minimal, reproducible example

Steps to reproduce

1. In the example, click the dropdown;
2. Wait for the options to load;
3. Scroll to the bottom to trigger further option loading;
4. Select one of the lazy-loaded options;
5. Press the reset button and observe the console;

Expected behavior

I would expect no error to appear in the console.
