*** Overview description ***
Type rendering is slightly off after an AJAX-driven reload of (partial) page
content.


*** Steps to reproduce ***
1) go to URL
http://storedev.apple.com/1-800-MY-APPLE/WebObjects/AppleStore.woa/wa/RSLID?mco=392EC8B&nplm=MA086LL%2FA
2) scroll down to the Reviews section and take a very close look at the first
post (as example)
3) switch to a different page of the reviews, then switch back to page 1
4) compare visual difference. Take screenshots if necessary.


*** Actual results ***
Text looks slightly different than it should; looks slightly different for the
first page's content compared to what it looks like before switching pages.


*** Expected result ***
Text to look the same, visually.


*** Additional information ***
- AJAX change is driven by a Dojo library, which uses Opacity to do the fade-in
and fade-out
- bug initially discovered in the latest public Safari
- I have sent two images of the first post, text scaled up two notches, to
Maciej Stachowiak. The first image shows the post after page load, the second
shows the post after switching Reviews pages back and forth. Visual differences
are easy to spot at this text size (I can send the screenshots to whoever wants
them, or ask Maciej for them).
