How to reproduce:
1. Open the attached project
2. Select Legs_Spider_Med@Legs_Spider_Med_Walk.fbx model
3. In inspector Animations tab find Motion
4. Change Root Motion Node to ROOT and Apply

Expected result: Loop match identification bulb is shown
Actual result: Loop match identification bulb is not shown

Not reproducible: 5.3.6f1

Notes after the fix:
-In Generic, you will not see any indication bulb if "Root Motion Node" is defined, and this is expected. One of the issues was that this bulb was displayed in this specific case.
-In Generic, when "Root Motion Node" is NOT defined, indication bulbs are now displayed as expected.
