FasterHopper Filter Fails for Stacked Items

Issue I've known about for a long time but I only pinpointed the fail case today: the filter does not apply to item entities stacked greater than the vanilla item stack size (i.e. merged with the plugin that uncaps item merging limits.) — Throwing out two stacks of sticks in quick succession throws out a merged stack of 128 sticks. The turbohopper (whose filter should prevent picking up sticks) picks up the excess stack size of 64 sticks until the stack size is back to its vanilla limit (64). Same result for three, four, or five stacks of sticks. — Throwing out single stacks of sticks one-by-one results in no breakage of the filter. Hopefully knowing the cause of this fail case leads to a fix because turbohoppers being able to be used as one-block filters would be very convenient. Couldn't find a matching report so making this just in case it's not yet documented/this is new. Video attached.
