Not sure if this is a bug or a missing functionality, but items do not seem to have that problem, as I was able to use an elixir of silvanus that was stored in its bag during dialog, so I'm leaning towards a bug :
Scrolls in containers in a character's inventory aren't seen by either the spell learning interface or the dialog interface.
To explicit my point further; I usually store and sort items into three containers : a backpack for utility items, another for spells, and a pouch for utility equipment and quest items. If a scroll of Detect Thoughts is in the bag, the dialog option to use it won't appear. Similarly, the wizard's "Learn more Spell/Translate Scroll to Spellbook" interface will not see the scrolls if they are in their backpack.
