Placeholder clears data from previous steps of wizard

Hello all!

I have a wizard form. On the first step I have an input field and on the second - a placeholder controller (an some other inputs). I have realized that, when I submiting a form on the third step, the data from the first step isn't passed. But if I remove the placeholder on the second step, everythind works fine. Could you explein me if it's wrong or not?

public function getSteps(): array
    {
        return [
            Step::make('Product ID')
                ->description('Write a product id you want to spy')
                ->schema([
                    TextInput::make('product_id')
                        ->required()
                        ->reactive()
                        ->default(158292376)
                ]),
            Step::make('Confirmation')
                ->description('Check a product one more time and confirm you want to spy it')
                ->schema([
                    Placeholder::make('product_id')
                        ->content(new HtmlString('<div>Are you sure?</div>')),
                    TextInput::make('product_id_one_more_time')
                        ->default(158292376)
                ]),
            Step::make('Notifications')
                ->description('Define what actions to be notifyed')
                ->schema([
                    Toggle::make('notify_if_product_name_changed'),
                ]),
        ];
    }
