User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:57.0) Gecko/20100101 Firefox/57.0
Build ID: 20171112125346

Steps to reproduce:

In firefox debugger.
Execution stopped because an exception.


Actual results:

"this" is optimized away! It can't be right that the only way to find the context actually is removed. 
And if I try to add this as an watch then that "this" points to window ( see other bug-report from me ) 


Expected results:

I think that "this" never should be optimized away. It is too important.
