[2.0.20] Inserter cannot drop faster on splitters than on belts anymore

[AVADII]

Factorio version 2.0.20

When an inserter is dropping items into a splitter it seems that normal, fast and express belts cannot be saturated.
This is different from version 1.1.
This problem doesn't occur when using turbo splitters.

Steps to reproduce:
Build a chest and a bulk stack inserter. Let the inserter drop items directly into a splitter from the side and look at the saturation of the outgoing belts.

I also made a video showcasing this issue.

I think it was a fun mechanic and would really appreciate it getting put back into the game, it makes train unloaders and the faster machines now so much more fun.

I also think I faintly remember a comment like 6 or 7 years back where someone was talking about this behavior being made more consistent after they made a bug report about it, indicating that this was put into the game deliberately at some point.

Thanks!

Yes it's indeed a duplicate.
But in the other post boskid says it's not a bug.

Well, i think it is because the behaviour of the 4 belt types is inconsistent and doesn't make sense.
There might be limitations what the current code can do - i understand - but the current solution isn't optimal to say the least.

I'd understand when it's too much work to fix this but saying it's not a bug is weird to me.
