+Subject: [PATCH] Don't tick markers
+
+Fixes https://github.com/PaperMC/Paper/issues/7276 and https://github.com/PaperMC/Paper/issues/8118
+by using a config option that, when set to false, does not add markers to the entity
+tick list at all and ignores 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. When the config option is set to true, markers are ticked as normal.
