Description Andrey Kosyakov 2011-10-25 05:02:59 PDT
There's a race condition in showObjectPopover() -- sometimes, popover may be hidden while a popover expression is being evaluated in the inspected page. In this case, _highlightElement becomes undefined and this._highlightElement.addStyleClass() call in showObjectPopover() results in an exception.
