It seems pretty sad, since I think it's a very useful feature for a
large class of pages -- particularly pages that are more "documents"
than "applications".

I wonder if it would be possible to disable the feature under
certain conditions, for example:
 * the page uses APIs that initiate scrolling from script, or
 * the page has handlers for scroll events, or
 * the page does both of the above
but leave the feature enabled for pages that don't do these things.

Based on what I've heard it seems like many of the cases where pages
are really broken involve some of those, although I haven't gone
through the bug lists.
