When you scroll down a long list, and when hover over the top items - the list scrolls up automatically.

I can't seem to reproduce this in v3 in Chrome or FF. Closing for now, but let me know if this is still an issue.
I found this happening on Chrome - the cause was the li elements having bottom margin:

Adding this to my CSS fixed the issue.
.vs__dropdown-option {
margin: 0;
}
