To reproduce:
1. Open attached project
2. Open the scene "Main"
3. Play the scene
4. Press "Log something" multiple times
Notice that the console shows that the variable "before" is increasing, while the variable "after" isn't. This happens because between "before" and "after" being increased, the handler throws an exception.
Expected result: Other handlers are still working, and the exception is reported to the console.
