Steps to reproduce: 1. Type something (for example, in a text field Bugzilla). The text should be short, to allow a lot of possible completions. 2. Press F5. Results: a suggestion popup appears, but its scroll bar has a disabled look (though it does work).
AFAICT this is a regression only in the sense that in TOT it happens in text controls since they are engine-based. In editable HTML, the behavior is the same in Safari 2.0.4 (and in shipping Mail).
