Stroustrup formatting is broken for nested `if`s with comments

[ArthaTi]

void main() {
    if (true) {
        if (true) { 
        }
        // This comment breaks formatting of the next line:
        else { 
        }
    }
    // Formatting below is OK
    else {
    }
}

Running dfmt --brace_style stroustrup on this file will outdent the first line with else on it. The issue does not occur on the other else, or if there isn't a comment before the else.
