fix: adjust linked filter to be left-right and do not link to new forked instances (#2913)

Browse Source 
* fix: adjust linked filter to be left-right and do not link to new forked instances
 - Assume that child filters know about their own forks
 - fixes #1874

* Remove appliesChunk|Layer for now
