Arrows fired into the side of bamboo or pointed dripstone never despawn

The bug

Arrows that have been fired into edge of bamboo are persisting in the world. Adding to lag, I would imagine, though I don't know how much at this point.

The single arrow was fired a while ago but not sure by what/who. The clusters of arrows were fired by a pair of pillagers more recently. All well past 5 minutes ago. Family server, stopped/restarted and arrows have stayed.
