Improper subtotal values for cart items in the cart view

Description

Plugin version: 34.0.8

When adding multiple options configured through this module to a single product - improper subtotal values appear in the cart view.
I have a restaurant with catering website that allows the customer to add custom extras to the food. Here is an image showing the product page with available extras:

As you can see the total is 17,00 zł
When I proceed to the cart view though - the subtotal is 12,00 zł

It appears that only one extra field is being taken into calculation.

Step-by-step reproduction instructions

1. Go to backoffice to create a field group inside the module settings.
2. Configure at least 3 checkbox fields that add flat value to the price.
3. Apply that config to any product.
4. Proceed to front office - to the product chosen in the last step.
5. Add at least 2 fields to the product.
6. Observe the price on the product page.
7. Add the product to the cart.
8. Proceed to the cart view.
9. Observe the subtotal of the previously added product.

I have already found a solution to this problem in the following file:
\woocommerce-product-addon\src\WooCommerce\Cart\CartHandler.php
function item_subtotal (line ~778)

Replace this:

	foreach ( $option_prices as $option ) {
		$option       = Helpers::translation_options( $option );
		$option_price = isset( $option['price'] ) ? $option['price'] : 0;
		if ( 0 === $option_price || ( ! isset( $option['apply'] ) || 'onetime' !== $option['apply'] ) ) {
			continue;
		}
		$price = isset( $option['discount'] ) && $option['discount'] > 0 ? $option['discount'] : $option_price;
		if ( ! empty( $price ) ) {
			$price = apply_filters( 'ppom_option_price', $price );
			$price = floatval( wp_strip_all_tags( $price ) );
		}
	}

With this:

	foreach ( $option_prices as $option ) {
		$option       = Helpers::translation_options( $option );
		$option_price = isset( $option['price'] ) ? (float) $option['price'] : 0;

		if ( $option_price === 0 || ( ! isset( $option['apply'] ) || 'onetime' !== $option['apply'] ) ) {
			continue;
		}

		$current_price = ( isset( $option['discount'] ) && $option['discount'] > 0 )
			? (float) $option['discount']
			: $option_price;

		$current_price = apply_filters( 'ppom_option_price', $current_price );
		$current_price = (float) wp_strip_all_tags( $current_price );

		$price += $current_price;
	}

It fixes a problem with setting the value of the subtotal by instead accummulating it
