[0.17.66] Inserter get stuck when using filtered Cargo wagon and multiple inputs

[OzoneGrif]

I have one chest and one inserter (can be blue or green, as long as it can hold more than one item in hand).
The destination is a cargo wagon, filtered by item types and limited.
The inserter gets stuck because it can't put all the held items in the reserved slots.

This is super easy to reproduce and occurs 100% of the time during gameplay (which is very annoying) :3

Here's a save and some screenshots :

Not a bug.
Anything more than stacksize in wagon is not inserted. your filter wil only work if:
1. set stack size of the inserter to 1
2. make a circuit network contraption to stop the inserter picking up any more items before the stack is full

Also if all item stack sizes divide neatly by (combined?) inserter stack sizes (they always do with 1, of course) - in the above example, with a single inserter, 10 should work ? -
and you never have any differently stack size inserters (or players) dropping/picking up items to/from the wagon ?
(EDIT : will probably break if inserter runs out of stuff to pick up / space to drop - what about setting all inserter stack sizes to be increasing prime numbers ? 1-3-5-7-11 for the first 5 ?)
