    Description

      Ecmascript template literals are not working correctly if there are nested strings inside.

      For example 

      `This is Text \nand this is newline`

      works just fine, but 

          let a = 123;
    let b = `x ${a} \ny`;
    print(b);

      gives an error "Expected token `(template tail)'"

      However, this same javascript code seems to evaluate correctly with QJSEngine

          QJSEngine jsEngine;
    QJSValue value = jsEngine.evaluate("let a = 123; let b = `x${a}\ny`; b;");

    qDebug() << value.toString(); // prints "x123\ny"

      Please find the attached example project which demonstrates this issue
