textarea placeholder newline

I need to add placeholder to text field in catalog item under service portal on page load, I tried in catalog client script with jquery and  Result: The placeholder text is not translated to the appropriate language. Works on: Chrome 62, IE10, Firefox 60. If you look at the HTML5 spec document for textarea ; you'll see that its placeholder attribute, is defined as: Any string that contains no line feed (U+000A, “LF”) or carriage return (U+000D, “CR”) characters. Placeholder: Placeholder text. Since no browsers support this, we active the plugin for all browsers, not just legacy browsers.
