[refactor] Remove component references from trees#534
Merged
Conversation
This refactor removes references to the `component` from trees in favor of using observers. We still have occasional memory leaks, and this eliminates one cycle of chains/observation. In the future when we drop 1.11 support we can use `didReceiveAttrs` to assign these values instead of observers.
