Description James Holland 2011-10-01 14:07:39 PDT
In a long page of tables, the last border at the bottom of the table sometimes does not show.

As you scroll through the page, you will see missing borders, but once you scroll back up the page, the borders have returned!

See screenshot attached for example beneath Superglue.

Confirmed that this issue can be seen in Mac Nightly r97062 and Mac Safari Version 5.1 (7534.48.3).

I tried to reproduce it on the latest WebKit but couldn't. Is it possible that it was fixed by bug 71550?
Comment 6 James Holland 2011-11-19 04:08:45 PST
I have just checked with the latest Nightly, definitely not fixed. If you run through all the tables you will still see some missing bottom borders, although there do seem to be fewer the page still shows 4 missing for me.
