If I left an item inside an item container, will it dissapear after certain time?

It is known that dropped items dissapear after a certain amount of hours.
What if your item is stored in any item container (chests, bookshelves, etc)? Will those dissapear as well?
Question is mainly for Baldur's Gate, I'm playing the Enhanced Edition though so I'm not sure if they made a change about that as well. Does this apply to Icewind Dale too? (notice the tags)
