441835 - iframe inside div with zero height overlaps following content

Status: NEW

(Core :: Layout, defect)

Description

[Simon Montagu :smontagu]

Attachment: Minimized testcase.

This may well be invalid, but I am reporting it because it occurs on a major news site in Israel, and was mentioned in a radio chat-show last week as a reason not to download Firefox 3.

In the given URL, and all articles on http://www.haaretz.co.il, the first few rows of talkbacks below the article are partly obscured by an iframe containing ad links. The iframe is inside a div with style="height: 0px".

Comparing other browsers, Safari 3.1.1 on Windows and OSX displays the iframe overlapping the talkbacks, but without most of its text so the effect is much less ugly; IE7 and Opera 9.21 show the talkbacks below the iframe.

In a standards-mode version of the minimized testcase, all browsers display the frames overlapping. In quirks mode, they overlap in Gecko and Safari, but not in Opera and IE.
