Reproduction steps:
1. Open project “LoopingTest”
2. Open scene “SampleScene”
3. Make sure the Inspector window is open
4. Enter Play mode
5. Wait for the animation to stop playing
6. Select “Grid\Tilemap” GameObject

Expected result: the animation doesn’t start playing again
Actual result: the animation starts playing on a loop

Reproducible with: 2022.2.4f1, 2023.1.0b2
Couldn’t test with: 2020.3.44f1, 2021.3.17f1 (TileAnimationFlags is introduced in the 2022.2 stream)

Notes:
- if the Inspector window isn’t open, the animation will play once after selecting the “Grid\Tilemap” GameObject
- selecting a different object in the scene after selecting the Tilemap, stops the animation loop
