Hello.
I always use backpacks and other containers to separate items by type. I store all projectiles and throwable items in a burlap sack and then drag the container to the hotbar. I open it during the fight and have access to the items I need to throw. Same works for scrolls, which I keep in one of the backpack types and also use from the hotbar.
After patch 9, both using scrolls from backpack (tested on chromatic orb) and throwing items from backpack doesn't work. Any attempt ends in a character just starting the throw animation and then - nothing.
Chromatic orb scroll is a separate case. You can only use this spell from the hotbar, because the spell itself has a sub-menu of different orb variants and it is designed only for the hotbar. Thus, casting this scroll from both backpack and inventory is impossible. I'll attach some footage below.
Here is me trying to throw a haste potion from the backpack:

Here is a sub-menu I was talking about. It only opens if you use the scroll directly from the hotbar. In any other case it doesn't work.
