annoyance: When first opening $scope tab in Elements view, have to select DOM element again

[christopherthielen]

Steps to reproduce

• Navigate to angular app (for example, https://angular-ui.github.io/ui-router/sample/#/ )
• Close Dev Tools
• Inspect an element
• Select the $scope view
• $scope data is not shown
• Select some other DOM element; now $scope data is shown

thanks @christopherthielen , hoping to get this resolved soon. this is a timing issue when we try to tell batarang to "redraw" and when it receives data from angular hint. sometimes the redraw event is received first and then the data later.
