Describe the Issue

When holding shift while moving the mouse it doesn't move the items from a backpack from Sophisticated Backpacks to the inventory. You can input items from the inventory while shift moving but you can't take them out without clicking each individual item (like vanilla).

Do you use any performance-enhancing mods (e.g. OptiFine) or custom server distributions (e.g. SpongeForge)?
