Subject: [PATCH] Don't tick markers
Fixes https://github.com/PaperMC/Paper/issues/7276 by not adding markers to the entity
tick list at all and ignoring them in Spigot's activation range checks. The entity tick
list is only used in the tick and tickPassenger methods, so we can safely not add the
markers to it.
