Description
Related forum post: https://forum.playcanvas.com/t/how-to-avoid-particles-system-to-teleport-particles/4664
See video where the velocity graph is modified but the bounds stay the same and the particles wrap from the top to the bottom.
Only when I make a different change such as ticking and unticking 'wrap', does the bound update in the preview.
This doesn't affect the launch tab/runtime calculation.

Research direction
Reproduce the particle-system preview issue by editing the velocity graph and observing whether the bounds refresh, then compare it with toggling “wrap,” which currently triggers an update. Trace the preview’s bounds-refresh path; done means graph edits immediately update the preview bounds while leaving the launch tab/runtime calculation unchanged.
