I was able to reproduce this bug: actually minecraft doesn't seem to handle the trading in case the item on the cursor would be going to exceed the max stack size as result of the trade. Shopkeepers however still handled the item movement to and from the players chest. This should be fixed in v1.27 in the way that we now as well don't run our trading code in case the item on the cursor would exceed the max stack size as result of the trade (just like minecraft).
