Keyboard navigation UnityEditor.IMGUI.Controls.TreeView becomes unresponsive if it contains many items
Steps to reproduce:
1. Open user attached project
2. Click Mainmenu > BugReport > Open TestCode Window
3. Click Window > Profiler
4. Enable "Profile Editor" and "Record" in Profiler window
5. Expand "Group 49" in TestCode window
6. Select "Item 49"
7. Hold Arrow key down
- Observe the UI lags and the profiler shows a lot of time is being spent in GUIUtility.ProcessEvent
Expected result: The UnityEditor.IMGUI.Controls.TreeView should not get slower with the amount of elements in the tree.
Reproduced in: 2018.2.0a1, 2018.1.0b6 2017.3.1p1, 2017.2.1p3
