Tiles are flipped when editing any Selection Inspector field after a negative Scale value was set for a Grid Selection

Steps to reproduce:

1. Open the attached "2D_FLIP_REPRO" project
2. Open the "Assets/UUM146002/UUM146002_Repro.unity" scene
3. Rebuild the scene (Tools > UUM146002 > 1. Build repro scene)
4. Open the Tile Palette window (Window > 2D > Tile Palette)
5. Dock the Tile Palette window so that both Tile Palette and Scene View are visible
6. Enable the Selection tool in the Tile Palette's toolbar
7. Select the 2 Tiles in the middle (Tools > UUM146002 > 2. Select the 2x2 block)
8. Change the Y scale to "-1" in the Inspector window
9. Change the X offset to "0.5" in the Inspector window
10. Observe the Tiles in the Scene View

Actual results: After step 8 the Tiles are mirrored vertically as expected, but the Inspector fields change on their own to Rotation (0, 180, 180) and Scale (-1, 1, 1). After step 9 the Tiles are also flipped horizontally in addition to being moved, when only an X offset is changed (no user input to flip the Tiles horizontally)

Expected results: The Inspector keeps the entered Rotation (0, 0, 0) and Scale (1, -1, 1), and changing Offset X only moves the Tiles without altering their orientation

Reproducible with versions: 6000.0.0f1, 6000.0.83f1, 6000.3.23f1, 6000.5.11f1, 6000.6.0f1, 6000.7.0a6

Tested on (OS): MacOS Silicon Tahoe 26.6.2

Notes:

• This is a high impact issue on the 2D Tiles workflow, because there was no input to flip the Sprites, only to move them by 0.5, yet the Tiles were flipped.
