Will adding output from a stream item trigger a payment?

Question

I have the following code that I need to make sure it is performance sensitive:

var $content = $(htmlString);

//Stop new element from triggering reflow? 
$content.css('display', 'none');

//add slide to DOM
$content.appendTo(options.els.$slider);

I can’t remember whether reflow is triggered by any manipulation of the DOM or if there are exceptions, such as adding a stream element to the DOM outside the element. Will the above code cause a re-melting if it options.els.$slideris in a stream?

display: none;
