Combobox: open/static changes onSelect type

[jamesarosen]

I have a Combobox that stores some complex value as its type:

const onChange = useCallback((widget: Widget) => {
  console.log('widget selected', widget)
}, [])

<Combobox onChange={onChange}>
  ...
  <Combobox.Options>
    {results.map((widget: Widget) => (
      <Combobox.Option value={widget} key={widget.id}>{widget.name}</Combobox.Option>
    )}
  </Combobox.Options>
</Combobox>

If I add open or static to the <Combobox>, then I get a TypeScript error:

No overload matches this call.
  The last overload gave the following error.
    ...
      Type 'undefined[]' is not assignable to type '{ description of Widget }[]'

This is true even if I set static multiple={false}. In fact, if I do that, I get an additional TypeScript error on multiple itself:

Type 'false' is not assignable to type 'true'.

Is this a bug? Or am I not understanding some intentional part of how static works?

The TypeScript error wasn't at all helpful, but the real issue is that static belongs on the Combobox.Options, not on the Combobox.
