Chrome Version: 55.0.2883.95
OS Version: OS X 10.11.6
Other browsers tested:
  Firefox 4.x: OK


What steps will reproduce the problem?
1. Type in the devtools console: 'let x = a;' (// Uncaught ReferenceError: a is not defined)
2. Then type in the devtools console: 'x = 2;' (// Uncaught ReferenceError: x is not defined)
3. Then type in the devtools console: 'let x = 2;' (// Uncaught SyntaxError: Identifier 'x' has already been declared)


What is the expected result?

I would expect to be able to either assign value to a variable or declare it without errors. Even after first ReferenceError.


What happens instead of that?

There are some errors thrown.
