How to reproduce:
1. Open the “Animator-CrossFade-Bug.zip“ proect
2. Open the “SampleScene“
3. Open the Game view, hierarchy, and the Animator windows
4. Enter Play Mode
5. Observe the Hierarchy and the Game view

Expected results: All Animator children get activated one at a time
Actual result: At one moment, all children get activated at once

Reproducible in: 2022.3.60f1, 6000.0.42f1, 6000.1.0b10, 6000.2.0a6

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- One split-off crossfade starts a few milliseconds later than the other one. This makes the second crossfade override the first crossfade and, in the process, causes the bug
- All the animations get activated until the transition finishes
