The browser window shrinks automatically to a small rectangle when any of the first page stories on aljazeera.net is viewed. When the window is resized to a normal view, the tabs only have their top halves shown. When the mouse pointer is moved on an unselected tab, the tab appears in full, but only its upper half is active (ie., can be clicked to switch to that tab). Once a tab is clicked and the page is switched to that tab, the tabs disappear again.
Please note that aljazeera.net is (unfortunately) IE-centric!
Currently using build 523.6+
Confirmed with a local debug build of WebKit r25670 with Safari 3 Public Beta v. 3.0.3 (522.12.1) on Mac OS X 10.4.10 (8R218).
The symptoms suggest to me that this may be an issue in Safari rather than WebKit. A malfunctioning tab bar, for instance, would seem to have little to do with WebKit.
It looks like there are at least two issues here. Clearly Safari should not be getting itself into a state where the tab bar is misrendering. I'll write up a separate radar to cover that issue shortly. The second is that when the page loads, an iframe at <http://jazad.aljazeera.net/jazcommerce/default.aspx?sThisPage=_1sis_reportsandanalysis_&BannerType=SponsorCMS> is loaded. This calls through to a function named unresizeFrame which is defined in <http://jazad.aljazeera.net/jazcommerce/CommerceFunctions.js> as:
It is this resize that is leading to problem.
Reduction is at http://bdash.net.nz/files/iframe-resizeTo/.
DOMWindow.resizeTo appears to always affect the outermost frame. In IE 7, the reduction results in the red iframe being resized to 10x10. In Safari it currently attempts to resize the browser window. window.top.myIframe is the DOMWindow associated with the iframe in each case.
I also discovered this problem on a malware site:
However, if you resize the shrunken window, the tabs are clipped:

Mark, do you still have this reduction sitting around anywhere? The URL is now invalid.

The bisect-builds script says this was fixed (progressed) between:
Fails: r36519 Works: r36635

Revision r36560 looks awfully suspicious: <http://trac.webkit.org/changeset/36560>
