[Shaders] Shader _Time value isn't updated when there isn't a Camera in the Scene
Shader _Time value isn't updated when there isn't a Camera in the Scene.
When you don't have a camera in the scene, just a Canvas set to Overlay, the shader animation (via shader code with _Time property) doesn't work. If you switch off Main Camera game object in testScene and close Scene View, leaving just Game View, and then hit Play, effect in Canvas will not be updated.
To repro:
1) Open attached project
2) Open testScene
3) Deactivate main camera game object and close Scene View tab
4) Enter playmode and see the shader animation (uses _Time) not playing on UI graphic
5) Activate camera game object and see animation working.
Reproduced in 5.3.8f1, 5.6.2p4, 2017.2.0b1.

Also happens in 2018.3.4f1.
Annoying when you only want to display UI using Screen Space - Overlay.

- OnPointerExit and OnPointerEnter is mistakenly called when an overlapping child Image is destroyed
- Dynamic text is rendered in the background when it is inside the <font> tag
- SerializeReference interface does not show CustomPropertyDrawer when it's inherited from another interface
- Rendering artifacts appear in the Editor when modifying the Reflection Probe box size
- [HDRP] XR Multipass calls BeginCameraRendering and EndCameraRendering for each pass of the same camera
Resolution Note (2019.3.X):
There is no nice way to force update the _Time or shader properties when there is no camera without rewriting a lot of systems which is not doable currently.
