Collected tests for problems with missing borders for TabContainer, in particular problems with the border between the tab buttons and the tab content.
Open TooltipDialog and make sure the horizontal border between tab buttons and content don't extend past the edge of the TabContainer. Also check that button for second tab (unselected tab) is visible on IE6.
Show Tooltip Dialog with TabContainer ▼Make sure the TabContainers below show the border between tab buttons and tab content. Previously it didn't show on initial page load, but showed after resize.
Make sure separating border doesn't disappear on zoom (not text-size increase/decrease but zoom). Problem used to occur on FF/windows and IE8.
