/**
* Ticket #14080
*
* - The bug happen on push event.<br/>
* - The changes in the DOM are css related.<br/>
* - It seems like when the class attribute is set on push, the textarea revert
* to the height defined by the rows attribute.<br/>
* - The size is reseted on onStateChange where the size is set to the one from
* the state. And it's because, when the user changes the text, at the next poll
* the state will confirm the change of the text, but the width and height
* didn't change in the state either client or server before the fix.
