Description Mike Sierra 2013-01-18 12:46:47 PST 
Open the URL and use the sliders to change either of the "pixels" or "points" values. The animation on the second sentence (the <span> element) is delayed by that of the overall <section> block, even when it inherits the parent's value.  (Both the parent <section> and child <span> element have a CSS transition applied to them, the latter as a way to indicate how relative keywords affect the inherited font-size value.)  Unclear as to the proper specified behavior in this case, but Firefox & Opera both transition smoothly.

Cute bug!
Comment 2 Mike Sierra 2013-01-18 15:17:04 PST 
Yes, adorable. It also appears Webkit & Opera transition stepping by integer values; Firefox is much smoother. (Occasionally shows up unwittingly when transition-property:all is in effect & the user zooms the page.)

Sadly, the testcase is now gone.
