I recently posted an idea regarding HTML tile height:
The current functionality of the HTML tile "height" feature can be quite frustrating. Having the height set for optimal viewing on one browser results in a scrollbar being see on another. Can dynamic height be added as a functionality? I would love to be able to choose for the HTML tile to dynamically size itself (height wise) to display all content within the tile.

Well over a year old.. but here is a script
var body = document.body,
html = document.documentElement;
var height = Math.max( body.scrollHeight, body.offsetHeight,
html.clientHeight, html.scrollHeight, html.offsetHeight );
