    ibusCandidatePopup: Clarify assignment in condition
    
    Most often it is a bug if the condition part of a for-loop contains the
    assignment operator rather than the comparison one, so tools rightfully
    emit a warning.
    
    Clarify that the assignment is intentional in this case by adding
    parentheses.
    
    Spotted by eslint.
