Affected Version:

What steps will reproduce the problem?

function foo() {
    var operator = "bar";
}
2. Push it for review
3. Check the difference (side by side or unified).

What is the expected output? What do you see instead?

operator should not be highlighted.

Instead, operator is highlighted with CSS class 'kwd'

Please provide any additional information below.

I checked:
