Stop this script should not kill thread

[griffpatch]

Expected Behavior

The stop this script block should exit out of a custom block and resume executing the script that called it.

Actual Behavior

This block is scripted to terminate the entire thread. I do have a fix for this in my local build (but it's based on my already modified code base)

Steps to Reproduce

Operating System and Browser

Any
