I said that on the extremely small set of pages that use the feature  
today, that those pages have essentially been designed such that  
jumping does not occur.  I'm not trying to generalize that to the  
whole Web.  I'm well aware that visual jumping could occur on poorly  
designed Web sites if the feature were to become wildly popular.

However don't underestimate how constrained most Web page layouts  
actually are.  When many items are placed in precise spots in a grid  
layout, then even if the font metrics of items at those grid positions  
are wildly different, there's not as much visual jumping as you might  
think.
