Similar behaviour of Hoppers here, except only some hoppers do it.
It is as if another hopper pushing items into it is deactivating it.
The same hopper sucking items from a chest behaves normally.
Sometimes a hopper will buildup and hold a relatively constant number of items until the hopper pushing into it empties.
Only seems to happen with horizontal hopper pipes, not vertical ones

Simple Hopper pipe. Some of them Behave as if deactivated by the hopper feeding it
