Isometric tiles changing order on tilemap depending on where brush is

-

*Steps to reproduce:*
# Open attached tilemaprepro.zip.
** *OR* set up a 2D URP project with a Isometric Tilemap in Hierarchy, and an Isometric Tile Palette with at least two tiles.
# With Isometric Palette open, select one tile and draw some onto the tilemap.
# Select the second tile, draw over some of the tiles you placed in Step 2.
# Select the first tile again, and hover your cursor *northwest* of your painted tiles. 

*Actual results:* Tiles seem to change order when the mouse enters this region.

*Expected results:* No change from how tiles were drawn on initially or how they're displayed when the mouse is in other regions of the scene view.

*Reproducible with versions:* 6000.1.0a8, 6000.0.31f1, 2022.3.53f1, 2021.3.45f1, 2021.2.0a1

*Tested on (OS):* Windows 11

*Notes:*
* Could repro with tools that involved painting tiles.
* Regarding Step 4, couldn't repro when the mouse was in any other direction on the grid.
* Tried with both default settings and with settings of Transparency Sort Axis mode - Custom Axis and Transparently Sort Axis - 0,1,0 in the Renderer 2D Data.

  1. Resolution Note:

    The Isometric Tilemap and Tiles should be set up correctly for the Tiles to sort correctly, which can be done by following the manual at:
    https://docs.unity3d.com/6000.0/Documentation/Manual/tilemaps/work-with-tilemaps/isometric-tilemaps/renderer/tilemap-renderer-isometric-modes.html

    In Chunk mode, the Sprites used should come from the same Texture or be atlased using a Sprite Atlas.

    In Individual mode, the Sprites should have the correct pivots set to be aligned with the Isometric grid.
