From Bugzilla Helper: User-Agent: Mozilla/4.6 [en-gb]C-CCK-MCD NetscapeOnline.co.uk (Win98; I) BuildID: 2000061311 When a window is shrunk horizontally, just as the right hand side reaches the'QA' in the top toolbar, the contents of the window cease to reflow or reformat. If one continues shrinking the window, contents (including any scrollbars) just begin to disappear off the right hand side. Reproducible: Always Steps to Reproduce: 1.Load an HTML file which contains enough to induce vertical and horizontal scrollbars in the browser. 2.Shrink the window horizontally. Actual Results: Notice that at a certain point (round about 'QA' in the toolbar) the horizontal scrollbar and page contents cease to adjust, and contents (including scrollbars) start to disappear. Expected Results: Contents should continue to reformat, and scrollbars should continue to adjust and be the last thing to disappear as the window shrinks.
