Revert 98139. This revert: - Fixes hover looting stacks of items into containers with an item limit less than the current amount on the stack. - Fixes the same issue for right-click looting. - Breaks drag-swapping two valid items between inventory and a container with an item limit less than the current amount on the stack (e.g. dragging a stack of engine components into a modular car engine slot that already has a component of a different tier - all but one item on the stack will be lost).
