An issue with the Trail effects in UIParticle

[linkongchen]

"Hello, I am also experiencing an issue with the trail effects in UIParticle.

Here is the situation: If I enable the 'Trails' module in the Particle System, it renders correctly without the UIParticle script. However, as soon as I attach the UIParticle component, the effect breaks.

This issue started occurring after upgrading to version 4.11.2. It was working perfectly fine in version 3.3.

I have uploaded a zip file (reproduction project) and a video for your reference."
