Issue description

I noticed an animation (or rather some tracks of it) not playing in my project after updating form 4.2 stable to 4.3dev5.
The animation in question is played from a AnimationPlayerNode, has a few keyframes that modify the scale property.
I have tried my best to isolate it in a minimal example in the attached project.

Note that I tried to make a very simple test from scratch on 4.3 beta2 playing a animation that modifies the scale property from an AnimationPlayer node and all worked correctly.

Steps to reproduce

• Open attached project with 4.2 stable and play
• Hover over circle, notice the scaling animation and sound playing
• Open the same project with 4.3 beta2
• Hover again and notice the scaling animation doesn't play, however the sound still plays (it is a different track but part of the same animation)

Please try in a recent version like beta2

The same issue is present if I try to update the attached project to 4.3 beta2. i have updated the bug description accordingly.

I found that there is a problem with the bezier track initialization on caching. I don't know why this was working in 4.2, but the issue may have become visible in 4.3 due to changes in deterministic and discrete mode behavior.

I sent #93785 as a fix.
