[Feature Request] Allow <Combobox.Input/> displayValue to be customized display component

[pkong-ds]

Description

Currently Combobox.Input displayValue only allow string type
I would like to render customizable component as displayValue too

Use Case(s)

Some example use cases can be found in tailwindUI combobox demo page

• in both cases, if displayValue is a customizable component, image/secondary text could be added to display
• IMO this use case is very common

With image	With secondary text

Proposed Usage

• allow an extra props to be ReactElement (and other props for other framework?); OR
• Expose another API like <Combobox.DisplayComponent /> where its children would be rendered as display?

Also, this displayComponent is expected to be shown while combobox is not active/focus/editing

displayValue: string;
displayReactComponent: ReactElement;

Alternatives Considered

I tried rendering <Combobox.Input /> as a <Fragment />, then render <input /> inside it, as suggested by doc

   <Combobox.Input
        as={Fragment}
        ...
      >
        <input />
          // tried putting custom displayComponent here, but lost some Combobox feature such as autocomplete 
      </Combobox.Input>

Thank you tailwind Team for making this amazing headless UI library!
