Unable to remove complex fields containers with nested complex fields

[smachi]

Version

• Carbon Fields: 3.3.2 and 3.4.0-beta1
• WordPress: 5.7
• PHP: 7.4.21

Expected Behavior

When adding a nested complex field and also conditional logic to the fields within the nested complex field, all seems to work as expected until I try to remove the parent container with the complex field's remove icon.

Actual Behavior

When I click the icon to remove the parent container, it shows a lot of errors at the browser's console and the meta box content disappears and the only way to make the meta box showing again is by reloading the page and losing changes. Also, if I try to save the page in that state, after reloading I can see that the container that I tried to remove is still there.

Container definition

			         Field::make( 'complex', self::$product_options_key, __( 'Setup product options', WPD_CONFIGURATOR_TEXT_DOMAIN ) )
