When trying to place item ghosts into an inventory via a proxy, it simply does not happen.

Mods to test it with:
https://mods.factorio.com/mod/SpidertronPatrols
https://mods.factorio.com/mod/orbital-cannon

You can't make requests via the proxy. my expectation was that it would place the request in the target entity, then show me the requests that are in the target.

For the orbital cannon it is an actual bug, because proxies are used to control access to the real inventory so you can never interact with it any other way, only via the proxy.

Post a simple save and steps to reproduce and add the version to the title please, see 3638.

The sample is any of those mods, or anything using a proxy inventory. There is no save requirement to reproduce it, just try placing an item ghost in a proxy inventory that is currently linked with anything. Spidertron patrols is a clean example.

After learning how item requests work, it may be more of an "unexpected/undefined" behavior thing between the item request entity and the proxy inventory.

Ghost item interactions through proxy container were intentionally disabled, similarily as character and space platform hub do not support those interactions. Rationale here is that i never verified if it would work correctly (gui handing item requests from an inventory owned by a different entity) and it would not work as expected when blueprinting since you would have an entity with item requests that does not preserve item requests in a blueprint.

I expected it to go towards the inventory that it is targeting. Maybe with a flag on the proxy inventory itself? If it needs a hint if the target inventory is anywhere near. It may break if the proxy is on a different surface.

After looking at it more, maybe with an exception of the linked chest as that can be on multiple surfaces all at once and that sounds like a pain to handle.
