POSSIBLE SOLUTION
Seems like this can be easily helped by using a Sprite Atlas. See the answer to the linked question: https://gamedev.stackexchange.com/questions/154980/unity-order-issue-with-tilemaprenderer-render -

Resolution Note (2018.3.X):
The reason why this occurs is because the Bush Tile is made up of 3 Sprites that come from different Textures. The default rendering in TilemapRenderer prioritizes rendering Sprites in the same Textures and batching them together to reduce the number of Draw Calls, before sorting the Tiles. This can be verified by looking at the Unity Frame Debugger to see how the Sprites are drawn.
To help with this issue, the Sprites used in the Tilemap can be atlassed to a single Texture so the sorting can happen. To do this:
-Create a Sprite Atlas in the Project Window
-Select the Sprite Atlas asset
-In the Sprite Atlas inspector, add the Bush Sprites under Objects to Pack
-In Project Settings/Editor, ensure that Sprite Packing is enabled (Always Enabled)
-Enter PlayMode and observe the BushTop Tilemap
Alternatively, with the soon to be released 2018.3 version of Unity, enabling Individual mode rendering for the TilemapRenderer would allow for individual sorting and rendering of the Sprites instead of batching them up together statically.
