Can't ship orders with a decimal qty < 1

[ArronKing]

Preconditions (*)

1. Magento 2.4.4
2. MSI
3. Additional stocks and sources setup (I have two additional sources, and one additional stock)
4. Simple product with qty uses decimals and min qty set to 0.2. In stock at the two additional sources.

Steps to reproduce (*)

1. Create two orders - one for 0.5 of the product. One for 4.5.
2. Create a shipment for each of the orders
3. In source selection, choose any source

Expected result (*)

1. Two shipments to be created

Actual result (*)

1. One shipment (4.5 qty) is created. One shipment never creates
2. On the shipment confirmation page, items is empty (see image below)
3. Saving this, returns you to source selection

Apologies - this isn't actually related to inventory. I've found the root cause and opened an issue / PR in the main Magento2 repository:

magento/magento2#35971
