Default opacity setting (1) breaks particle rendering in WebKit (safari)

Above are two screenshots, the former taken in Chrome (macOS client), the latter taken in safari (macOS & iPadOS have same result). Exact same code, exact same options.

The Chrome app for iPad also displays this abnormal behavior, likely because it is using WebKit to render the content as well.

I am not sure what the underlying cause is, or if this library is maintained anymore. But for anyone else trying to get this to work properly on mobile Apple devices, you need to have the opacity setting in the velocity layer options set to 0.98 or lower to make it normal again.
