html - Insert line break inside placeholder attribute of a textarea?

I have tried a few approaches but none worked. Does anyone know a the nifty trick to get around this?

<textarea placeholder='This is a line 
 this should be a new line'></textarea>

<textarea placeholder='This is a line     
should this be a new line?'></textarea> <!-- this works in chrome apparently -->

UPDATE: It doesn't work in chrome. It was just the textarea width.

See: http://jsfiddle.net/pdXRx/

You can insert a new line html entity &#10; inside the placeholder attribute:

<textarea name="foo" placeholder="hello you&#10;Second line&#10;Third line"></textarea>
