A bundle in the output of a crafting recipe is not updated if the bundle in the crafting grid has its contents changed

Currently, a bundle that is being dyed in the crafting grid can have its contents changed with no effect on the outputted dyed bundle, as long as the bundle itself is not removed from the grid. This can lead to item duplication or deletion.

 

Perform the following experiments:

Item duplication:

1. Place a bundle filled with 64 diamonds and a dye of your choice into the crafting grid.
2. Observe that the output of this crafting recipe will be a dyed bundle filled with 64 diamonds
3. Before clicking on the output of the craft, remove all the diamonds from the bundle in the crafting grid
4. Notice how the bundle is still shown as being full in the output
5. Take the dyed bundle from the crafting output and notice that the bundle is still filled rather than being empty, thus duplicating all 64 diamonds.

Conversely, this can also delete items by performing the following:

1. Place an empty bundle and a dye of your choice into the crafting grid.
2. Observe that the output of this crafting recipe will be a dyed, empty bundle
3. Before clicking on the output of the craft, add a stack of 64 diamonds to the bundle in the crafting grid
4. Notice how the bundle is still shown as being empty in the output
5. Take the dyed bundle from the crafting output and notice that the bundle is still empty rather than being full, thus deleting all 64 diamonds.
