The tiapp.xml that is open in the TiApp Editor view cannot be fully scrolled until the view is resized. See the attached gif for an example.
Steps to reproduce issue:
1. Open a tiapp.xml in Studio
2. Scroll the tiapp.xml in the TiApp Editor view (You may need services enabled for extra length)
The tiapp.xml scrolls to the bottom and all services are visible
The tiapp.xml does not scroll to the bottom
Once the view is resized (by dragging the bar at the botton of the view, between the tiapp and console), then it can be fully scrolled.
