Browser content has to support all the features and they add up pretty quickly. For example a large scrolling list with thousands of items can be solved by a gamedev by mandating all content be the same size and applying a tiling rule. A list in a webapp is likely to be held to a higher standard and so needs to consider heuristics to find the position of content, dynamic updates, etc.
