On the linked page, Safari 3 gives the top row and the bottom row far too much vertical space. Switching to a quirks or transitional DTD fixes the issue (the page has a strict dtd). Adding line-height:0 and font-size:1px to the TDs on the top and the bottom also fixes the issue. The page looks fine on FF/IE.
Created attachment 461592 [details] Safari 15.6 matches with other browsers I manage to find this URL on Wayback Archive and turn it into JSFiddle below: Link - https://jsfiddle.net/079123bj/show I am not able to reproduce this bug in Safari 15.6 and it matches with other browser as can be seen in attached screenshot. I am going to mark this as RESOLVED CONFIGURATION CHANGED, assuming it was fixed along the way. Thanks!
NOTE - I added the strict DTD in below JSFiddle and there was no difference: Link - https://jsfiddle.net/ez3yprd4/show
