[Godot 4.3-4.4beta4] GPUParticle2D spawned out of camera zoom does not animate correctly

Tested versions

Reproducible in 4.3 - 4.4beta4, Windows + Linux, AMD and Nvidia

System information

(Forward+) Godot 4.3 - 4.4beta4, Windows 11, Linux KDE NEON, AMD and Nvidia gpu

Issue description

Creating particles out of screen does not play alpha animations correctly. The example and the video shows how creating particles inside the camera zoom animate OK (fade until disappear), but when creating outside camera zoom, they "just start animating late, and then disappear"

Steps to reproduce

In general:

1. Spawn particles outside camera
2. wait some seconds so the animation progress
3. find the particles outside the camera, and see the problem

Using the project attached:

1. right click to spawn 5 GPU Particles
2. zoom out (scroll wheel) to see the 4 particles spawned outside the camera
3. animation get broken

Minimal reproduction project (MRP)

bug-gpu-particle-2d.zip

Open the attached bug-gpu-particle-2d.zip project and reproduce the issue by spawning GPU Particles, zooming out, and observing particles created outside the camera. Start by tracing the GPUParticle2D processing and camera-visibility behavior. Done means particles spawned outside the camera animate their alpha progression correctly, matching particles spawned within the camera.
