### Godot version

4.2 1ba920f

### System information

Windows 10.0.19045 - Vulkan (Forward+) - dedicated NVIDIA GeForce GTX 1060 (NVIDIA; 30.0.15.1403) - Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz (8 Threads)

### Issue description

```GDScript
func _ready() -> void:
	$AnimationPlayer.play("new_animation")
	$AnimationPlayer.advance(0)
```
The animation has a single track with Update Mode set to discrete. It does not play, no matter the argument used.
Removing `advance()` will make it play.

Works correctly in rc1.

### Steps to reproduce

1. Run MRP on master
2. Run MRP in 4.2 rc1
