Repeating command block summoning piglins/villagers causes memory usage to constantly increase

Tested on 1.19.2 with lithium and 1.19.3 vanilla

Reproduction steps:

1. Place a repeating command block with command:

/summon piglin ~ ~30 ~

2. Activate it and just wait (for about 40 minutes). Memory usage will increase slowly and after it reaches 100%, the game is stuck.

Maybe memory leak?

Besides, piglins crossing nether portal have the same problem, and it affects some cross-dimension zombified piglin farm design.
