On varied setups of item entity velocity, sometimes only one hopper of a pair will pick up an item. This behavior is unpredictable.

Steps to Reproduce:

• Step 1: Download attached world;
• Step 2: Test the presented setups accordingly;
• Step 3: Note which items were collected by their respective item filters.

Observed Results:

Sometimes, no hopper pair picks up their respective filtered items. This may be caused by the item entity not ticking above the hopper and is NOT the object of this bug report.

Other times, only ONE of the hoppers in a pair picks up their respective filtered items (described in world download as "break parity", see video 1). Furthermore, as can be seen in the various setups presented, further away hopper pairs may or may not work as intended, which discards the possibility of item entity misalignment. This IS the object of this bug report.

Expected Results:
Either:

• Both hoppers in a pair collect their filtered items; or
• Neither hoppers in a pair collect their filtered items, possibly due to, as discussed in Observed Results, item entities not ticking above hoppers.

Additional information:

There were, in testing, other setups of water streams with different parity break points. However, they are redundant for the purposes of this bug report. The world download for all tested setups can be attached if requested.
