DESCRIPTION: The test case is a sidebar demo XUL file that sets visibility dynamically as a workaround for bug 9013. However, the setting only works the first time. After you set it to visible, and then hidden, it can't be shown again. STEPS TO REPRODUCE: * Download the four files in http://www.fas.harvard.edu/~dbaron/nstmp/M9-4-bad1/ * load when-com.xul in viewer or in the sidebar of apprunner (by editing chrome://sidebar/content/sidebar-browser.rdf and giving <NC:height>170px</NC:height> as well. * Click "Add" (...wait until stuff shows up) * Click "List" (... "") * Click "Add" ACTUAL RESULTS: After clicking "Add" the second time, nothing shows up. EXPECTED RESULTS: Can keep switching between the two panels ad infinitum and they will still always show up. BUILDS TESTED: * Linux, apprunner, 1999-08-16-08-M9 * Linux, viewer, 1999-08-16-08-M9. ADDITIONAL INFORMATION: You don't know a workaround for this (or bug 9013), do you?

Probably a duplicate of 10402?

chrisd, can you check Win and Mac please?

I think this should be resolved as a dup of bug 13047, but I'm not sure...
