We need a release before each of the void returns, otherwise we end up with a leaked AIMessageTabItem whenever anyone clicks the close button in the tab bar (Which leaks a AIChat and all associated views in return). I don't have commit privileges, but several people here do, so I thought I'd ask on the list.
