Navigating dropdown with arrow keys jumps unexpectedly when item is hovered & active

Repro

You can use https://multiselect.janosh.dev/ and use the first example.

Open the dropdown, and hover over a language, for example, F# so that it is active and has the blue background. Then start pressing the up/down arrow and you see the behavior.

Good catch! Thanks for raising an issue.

Might be due to multiple event handlers interfering with each other. Maybe the scroll handler is triggered by keeping the active option in view in the dropdown list which triggers the mouseover handler since the scrolling happens to move the mouse over another option or sth like that. Don't have time to debug this right away. If anyone wants to try, that'd be great.
