2D -view bugs out when user moves mouse above it after double-clicking 'Box' component

Steps to recreate:

1. Open Design Studio and create new empty project file (General -> Empty)
2. From Assets -view, import Box from Quick3DAssets:
   1. rta_test_projects -> Assets -> asset_import -> Quick3DAssets -> Box -> source scene -> Box.FBX
3. Double-click the Box -component in the Component -view
4. When Box is viewable in the 2D -view, move mouse above it

The Box -component will disappear from the 2D -view. This bug only happens the first time the Box -component is added to the Components. If user changes the workspace during the bug, the Box -component will appear in the 2D -view again.
