how to add hover text in one place in a question without any character limits

Hi, 

I am wondering if there is a way to add hover text to the question in the survey, in the question instructions. For example “Hover here...” This is the html code used to add custom hover text, but it is cutting off after max # of characters. How do you show longer hover text? 

Code:

<i><u><span title=”Random text">Hover</span></u> here.</i>

Thanks!
