Bug with quantity in cart with v2.2.4

Version 2.2.4 seems to have introduced a bug into the cart page. The quantity being ordered appears to show the stock value. Reverting back to 2.2.3 makes the quantity work again. I’m using the Event Tickets plugin too, but that doesn’t seem to be the cause of the issue as (1) it works fine with the Twenty Twenty One theme and (2) works fine with v2.2.3.
