While working with a diagram editor (the function definitions editor in this case), every time I need to click on a different application (like the test script) or right-click to display a context menu, the properties view would lose it's context and go back to showing the resource's properties. This is really annoying. We need to do a better job of maintaining the synchronization between the properties view context and the current appropriate selection, recognizing when focus changes due to a user selection or just an automatic focus gain (by the resource in this case) due to a temporary focus loss (by the diagram object).
