[2.0.15] Ghost cursor behavior is completely broken in remote viewed vehicles (Spidertron)

[ividyon]

When using the ghost cursor to request items directly into a Spidertron (probably also Tank), the "request remaining" numbers get extremely jumbled when the items in the vehicle are automatically sorted.

This leads to behaviors such as:

• Click into a random tile to place 100 express belts. The first placed 4 belts jump to the start of the inventory, losing the remaining "96", and so bots no longer try to fill the remaining 96.
• Add more ghost cursor requests while there is a pending requests such as "13 Quality 3 modules". If the new requested item gets sorted before the existing request, the "13" will now be on another tile, even if it doesn't make sense, such as a full item stack.
• Right-click to set many trash requests on many stacks. As the bots arrive, some "X" icons will remain in the UI on already emptied slots, until you close and reopen the GUI. Some trash requests will never be fulfilled.

It's hard to put into words, but if you just very quickly try to add or remove a bunch of bot requests to the vehicle, it very quickly becomes apparent what's broken.

The behavior appears to be equally poor when not actively viewing the GUI. (i.e. add 50 Rare Quality 3 modules to Spidertron, close the interface, bots come to deliver 50 modules, but after the 1st delivery of 4 modules all the other bots cancel their task and depart, and the Spidertron ends upw ith only 4 modules)
