tileset painting z-index issues in editor

[hyperglow]

Ubuntu Linux 64bit

Tiles don't get painted in correct order in the editor. This happend the first time after I painted several tiles without problems. Maybe its the tilesize? The running game shows the correct tile z-depth... Check the screenshot.

Steps to reproduce:

Link to minimal example project (optional but very welcome):

👍 I can reproduce, sometimes newly painted regions of the tilemap would cover existing graphics with a higher z-index and position in the tree.

Edit: Actually, I'm talking of a bit different issue, but I guess the two are connected.

I tried to recreate in a new scene and i got the same problem.
zip of the project is here:

Looks like it's an issue with quadrants repainting 😄

Edit, I'll put other findings here aswell

Edit 2 - already fixed, all notes are now commented out

@hyperglow ~ Playing around with your demo, if you do

extends TileMap

func _ready():
    set_process_input(true)

func _input(event):
    if event.type == InputEvent.MOUSE_BUTTON:
        set_cell(30, 0, -1)

And click on the screen in-game the same issue occurs.
