Is custom simulation space broken?

[MaxMaletin]

I am updating from 3.3.9, and since then the behaviour of custom simulation space seems to have changed. I've got a particle effect inside a scroll rect with simulation space set to custom. When I move the scrollrect, I expect particles to just move with it, preserving their shape, but instead they move up and down way too far. It looks like this is a bug, or maybe custom simulation space is not supported in the current version?

Expected behaviour: particles keep moving up and down in this sin curve like pattern when I scroll

Observed behaviour: particles move all over the screen.

Also, scene preview breaks

I have modified the included demo scene to show this behaviour. To reproduce, open the scene and scroll up and down.

Thank you for your reporting!

Unfortunately, it is currently (4.6.3) not working correctly in custom simulation space.
