this is a table with a tbody that has a fixed height and overflow set to scroll. the TRs have a background color.

in previous versions of FF, the row background color would not bleed through, but in FF3 (tested FF3 RC3 on Windows and Mac), it does bleed through

screenshot of FF3 (RC3) vs screenshot of FF2. Tested on Mac and Windows, both exhibit the same problem.

note that setting the table to display to "inline:block" and setting the tbody to display "block" fixes this problem, but introduces a new problem with the table headers.

try with a display:block on the tbody and display:inline-block on the thead (fixes the overflow, but introduces other problems)
