Issue description
When using ore sorters on a mining site, with output connected to loose storage, my trucks won't deliver their mixed load to the sorter when one of the output is full. Even if there's lot of space in the sorter input. The sorter appears as "partially stuck", but does not accept cargo anymore.
In this savefile, at my copper mine, the copper output is full, and the loose storage connected to it is full.
Ore sorter input is only 5% full, but the truck seen on the right is stuck with it's mixed cargo of copper ore and stones.
I think the trucks should continue to dump their mixed cargo in the input tray until it's full. Or maybe it's not how it's intended to work.

Reproduction steps
1- Load attached save
2- Have a look at the sorter on the right side of the map, near the copper mine
3- Have a look at the stuck truck
