## Issue
Tom seeing crashes on the line that was trying to remove the script, saying it's not a child of that node.
## Changes
- I'm guessing the found `fjs` sometimes is not in `head`, but we always remove from `head` during cleanup. Just append to the bottom of head, and remove from head. I think script order doesn't matter if we are injecting at runtime?
- Fixed effect dependency while at it (the latest PR removed the need to check for `type`).
