markers dont update position while riding other entities
Expected behavior
When summoning a moving entity with a marker as a passenger, the marker should constantly update to the location of the entity it is riding
Observed/Actual behavior
Passenger markers do not update their position while riding other entities, causing them to stay in the position they were spawned at

Adding a config option to disable #7299 may fix this issue
Paper actively removes the marker entity from the ticking list as an optimisation. This either might be worth to add a configuration option for or just straight up remove said optimisation. Really up to whoever opens the PR and the reviewers 👍
Currently working on a fix to add a config option to enable/disable this optimization

I assume you are not working on this anymore? Is someone else able to take over?

I have the fix written, but I've been busy and haven't had a chance to commit & PR. Should have some time this weekend.
