1. Use $already_reduced_stock instead of also considering $refunded_item_quantity while deleting orders. This will bring back part of #27504 again, but for now this seems to be the best solution for countering #28605. It needs discussion whether deleting a line item completely should also undo any refund related changes on it or not.
2. Also mark `stock_reduced` flag on order if any of the line item has any `_reduced_stock` flag. This will allow for stock restoring logic to work properly when order is cancelled.
3. Only adjust line item stock when order is in `processing`, `completed` or `on-hold` status state, because we need to reduce stocks on these status only. Stock adjustments in refunds or when changing statuses is already taken care of by their specific hooks.
Earlier, we were just showing an "Usage limit reached message", however in some cases, specially when user is logged in, we can also ask them to go to MyAccount page and cancel order if they'd like to (to free up the coupon). This will hopefully make for a better user experience.
We hold coupons when payment is failed if the setting "hold stock for checkout" is enabled for some minutes. This is to allow the customers to try again if they want, and to give time to complete payment for gateways where it could take some time.
Unfortunately this cause for some bad UX user retries by starting the order from scratch again, and then if they apply the coupon, usage limit gets hit because the earlier coupon is still held and is counted towards the usage. This commit improves the error message in these cases when usage is applied per customer and is hit, by stating to go to my account to complete/cancel payment (in case of logged in user) or to wait for some time in case of guest users.
This commit adds the 'Select a country / region...' text as a placeholder text displayed in the country select field indicating to the user that they need to select a country. This is only needed when the option ¨Default customer location" is set to "No location by default".
This commit removes the setting "Page style" from WooCommerce -> Settings -> Payments -> PayPal Standard. This setting was used to define the value of the parameter "page_style" passed to the PayPal Standard API, but PayPal deprecated this parameter and ignores it. According to PayPal in https://developer.paypal.com/docs/paypal-payments-standard/integration-guide/Appx-websitestandard-htmlvariables/?mark=page_style#deprecated-variables: "Deprecated variables are ignored when you pass them to PayPal". In the same link, you can see that "page_style" is included in the list of deprecated parameters.
This commit replaces double quotes with single quotes inside a MySQL query to avoid a syntax error when the SQL mode ANSI_QUOTES is enabled in MySQL. When this mode is enabled, MySQL treats double quotes as identifiers (like the backtick character) instead of as string delimiters. Before this change, sites running with this mode enabled wouldn't be able to add products to orders created manually in the admin as the modified query would fail (other places that also use product search including variations would fail as well). The commit that introduced this issue shipped in WC 4.5.0 (see https://github.com/woocommerce/woocommerce/pull/27171).
