once inside Blade component behaving incorrectly

[browner12]

The once() function is not operating correctly when inside a Blade component. I'm thinking this is a bug, because the README says it should only execute once "per request".

To recreate, make a simple component:

namespace App\View\Components\Admin\Buttons;

use Illuminate\View\Component;

class Number extends Component
{
    /**
     * Create a new component instance.
     */
    public function __construct() {}

    /**
     * Get the view / contents that represent the component.
     */
    public function render(): string
    {
        return once(fn() => rand(0, 100));
    }
}

Then use this component multiple times in a view:

<x-number></x-number>
<x-number></x-number>
<x-number></x-number>
<x-number></x-number>

Each of these is coming back with a different random number.
