1.open the given URL in a 1.0 release
2.open the URL in a trunk release
3.notice how in the 1.0 there is no space under the "ad banner", while in the

If it's a bug in the html please tell me, but I can see none myself.

I don't see a difference in how this is renderd in 1.0 and in a trunk build, but
either way it's not a DOM problem, so over to layout but from what I can see
this is WORKSFORME.

The difference is tiny, but nonetheless is noticeable and I can't find no reason
for it, please correct me if 1.0 is actually wrong and displays wrong html code
right just by chance =)
(else is a regression ^_^)

 I could see the problem with the latest trunk build. I see there is an extra 
gap between the "add banner" and the buttons. I think there is a dupe of this 
bug.

Attachment: IFRAME testcase

Creating a testcase I noticed that the problem appars only when the IFRAME in
inside a TABLE/TR/TD tag.

Thous could be a dubplicate of bug 155174 but here the extra space is inside the
IFRAME, not inside the TD and outside of the IFRAME.
But it is ideed a dup: also this bug deends on IFRAME's FRAMEBORDER=0 it seems.

Attachment: IFRAME testcase, with and without FRAMEBORDER=0

This adds a test suggested by bug 155174

Comment 9

[Lapo Luchini]

No, bug 155174 is right and I'm wrong: the extra space is in the table indeed.

So.... the table with borders is 66px tall.  The one without is 62px tall.  What
is the bug?

No response, no problem that I can see.  Marking worksforme.
