* SUMMARY When loading a particular page on usps.com, the vertical scrollbar may become detached. Forcing a repaint fixes the issue. * STEPS TO REPRODUCE 1. Launch Safari/WebKit. 2. Resize browser to 709x740 (full window width/height). 3. Open test page. 4. If vertical scrollbar is drawn and then drawn over, hit Reload until the issue appears. * EXPECTED RESULTS The vertical scrollbar should be repainted when it's removed when loading the page. * ACTUAL RESULTS The vertical scrollbar is not repainted when it's removed during page loading. * REGRESSION Can't test Safari 2.0.4 (419.3) with the 3.0 beta installed. * NOTES Tested with Safari 3.0 (522.11) on Mac OS X 10.4.9 (8P135) with a local debug build of WebKit r23546.

This still reproduces for me with Safari 4.0.4 on 10.4.11 using attachment 15066 [details]. I think it may be timing dependent, e.g., may depend on a slower connection or loading the page on a slower Mac. You may also have to reload the page a couple times to get it to reproduce.
