yes, invoices for cancelled subscriptions remain open and payable unless you explicitly void the invoices as well, it can be a problem

generally the best solution is probably to use https://stripe.com/docs/api/invoices/list?lang=curl#list_invoices-subscription in your webhook handler for the subscription cancellation and void any open ones (https://stripe.com/docs/api/invoices/void?lang=curl)
