Problem description

When using the blockPreviews for Builder the reactivity in the modal form doesn't work once the block is saved.

Expected behavior

Same as without blockPreviews

Steps to reproduce

See https://github.com/martin-ro/block-builder (UserResource)

or

add this to a from:

Forms\Components\Builder::make('blocks')
                    ->blockPreviews()
                    ->schema([
                        Forms\Components\Builder\Block::make('test')
                            ->preview('components.test')
                            ->schema([
                                Forms\Components\Checkbox::make('is_company')
                                    ->live(),

                                Forms\Components\TextInput::make('company_name')
                                    ->hidden(fn(Forms\Get $get): bool => !$get('is_company'))
                            ])
                    ])

Another observation I just made is that wrapping components in for example a group or fieldset reactivity works inside it. So this is only broken for "top level" components.
