UnityEditor should use the rendering settings of the platform it is used in.

The rendering path currently used by the editor should reflect the target platform. With the current setup, what you see in the game view does not reflect what you will actually see in the built version of the game, which contradicts many other aspects of the Editor’s target platform. Currently, the only ways to view the game with the mobile rendering path in the editor are to either change the standalone rendering path, or to change the actual camera’s rendering path.

This leads to confusion when using the camera’s depth texture in shaders. If the mobile path is set to forward while standalone is set to deferred, the depth textures will still function properly in the editor when targeting mobile platforms. Once you build the game for mobile however, the depth textures will stop working because you need to tell the camera to render the depth via script.
