AsyncSelect: defaultOptions should use current input value on first call

[mcintyre94]

When using <AsyncSelect> we can have the options loaded by calling loadOptions when the input is first opened by setting defaultOptions to true.

But on that first open the inputValue doesn't seem to be getting passed to the loadOptions call. This means that if the user was typing in the input, and we've saved their partial input, when they re-focus the input the options presented don't match their input.

Here I type "re" and the filtered options are loaded correctly. I blur the input, leaving "re" as the input value. When I re-focus it, the options presented are the defaults before I typed anything, not those I had for the "re" input previously.

I think that defaultOptions: true should be calling loadOptions with the current value of inputValue every time the input is re-selected, so that the user is presented with the valid options for their current input.

If anyone else has this issue, as a workaround you can set onFocus to call onInputChange using a ref. Example: https://codesandbox.io/s/codesandboxer-example-workaround-8sqwt3?file=/example.tsx

    <AsyncSelect
      cacheOptions
      defaultOptions
      loadOptions={promiseOptions}
      inputValue={search}
      onInputChange={onInputChange}
      ref={(ref) => (selectRef.current = ref)} // const selectRef = useRef<Select | null>(null);
      onFocus={() =>
        selectRef?.current?.onInputChange(search, {
          prevInputValue: "",
          action: "set-value"
        })
      }
    />
