Basic issue with headlessui ComboBox

[yanshay]

I'm using headlessui with preact and so far it worked fine.
Now I tried to use ComboBox.

I took and copied as is the basic example from headlessui web site at https://headlessui.com/react/combobox and trying to use the most basic use case of a ComboBox.

The issue I see is that after some filtering is applied by typing text into the edit, and then using backspace to delete the filter, when cycling using arrow keys through the full list several items are highlighted together, as if some internal headlessui state went out of sync.

The only difference between their running example and mine is that they probably use react and I'm using preact.

Is there a known issue or workaround to that?
