Hopper Minecart unloaders severely impacted by EAR
Expected behavior
Hopper Minecarts would pull from containers above, when present. The tick decimation from the EAR should only affect the time to detect a container while still allowing full speed transfers once started.
Observed/Actual behavior
When the player is outside the misc entity activation range the hopper minecarts only pull items very slowly. This is problem for larger farms (e.g. sand quarries) where the unload stations are at the edges of the moving quarry.
Steps/models to reproduce

The left design is the simplest exhibiting the problem. The right design is representative of the unload station from the sane quarry by TT (https://www.youtube.com/watch?v=T9kFmq1aXX0)
Place items in the top container and move more than misc activation range away. For greater realism, move the top minecart into position from misc activation range away.

I crated a patch proposal that grants immunity to hopper minecarts while they are pulling items. I will add the PR number here in a comment.
