Issue: [bug]: combobox options are disabled by default
Labels: bug

### Describe the bug

Even after installing the popover and command components that are required for combobox, the options from the combobox are not selectable.

I have used the default code from the documentation only. Here's the entire code for the reference: 

```js
import { Check, ChevronsUpDown } from "lucide-react";
import * as React from "react";

import { Button } from "@/components/ui/button";
import {
  Command,
  CommandEmpty,
  CommandGroup,
  CommandInput,
  CommandItem,
  CommandList,
} from "@/components/ui/command";
import {
  Popover,
  PopoverContent,
  PopoverTrigger,
} from "@/components/ui/popover";
import { cn } from "@/lib/utils";

const frameworks = [
  {
    value: "next.js",
    label: "Next.js",
  },
  {
    value: "sveltekit",
    label: "SvelteKit",
  },
  {
    value: "nuxt.js",
    label: "Nuxt.js",
  },
  {
    value: "remix",
    label: "Remix",
  },
  {
    value: "astro",
    label: "Astro",
  },
];

export default function App() {
  const [open, setOpen] = React.useState(false);
  const [value, setValue] = React.useState("");

  return (
    <div className="flex justify-center items-center h-screen">
      <Popover open={open} onOpenChange={setOpen}>
        <PopoverTrigger asChild>
          <Button
            variant="outline"
            role="combobox"
            aria-expanded={open}
            className="w-[200px] justify-between"
          >
            {value
              ? frameworks.find((framework) => framework.value === value)?.label
              : "Select framework..."}
            <ChevronsUpDown className="ml-2 h-4 w-4 shrink-0 opacity-50" />
          </Button>
        </PopoverTrigger>
        <PopoverContent className="w-[200px] p-0">
          <Command>
            <CommandInput placeholder="Search framework..." />
            <CommandEmpty>No framework found.</CommandEmpty>
            <CommandGroup>
              {frameworks.map((framework) => (
                <CommandList key={framework.value}>
                  <CommandItem
                    value={framework.value}
                    onSelect={(currentValue) => {
                      setValue(currentValue === value ? "" : currentValue);
                      setOpen(false);
                    }}
                  >
                    <Check
                      className={cn(
                        "mr-2 h-4 w-4",
                        value === framework.value ? "opacity-100" : "opacity-0"
                      )}
                    />
                    {framework.label}
                  </CommandItem>
                </CommandList>
              ))}
            </CommandGroup>
          </Command>
        </PopoverContent>
      </Popover>
    </div>
  );
}

```
