Steps to reproduce:

1. Open attached project
2. Open scene "test"
3. Select "Cube" in hieararchy
4. Add RectTransform component
5. Notice error in console: In order to call GetTransformInfoExpectUpToDate, RendererUpdateManager.UpdateAll must be called first
Also, from now on, selecting that component will start continuously printing this error to console. To add to that, RectTransform bounds won't show up

Seems to happen when adding rect transform to object which has mesh renderer
