Caused by 7688677e29, which replaced `DRW_draw_depth_object` with
`DRW_draw_depth_loop`.
`DRW_draw_depth_object` simply rendered the object without actually
using the DRW manager capabilities.
Now, with `DRW_draw_depth_loop`, the depth is rendered based on what
the engine sees with overlays disabled, which doesn't hide the
particles.
The solution to this issue is to skip particle rendering in the overlay
engine in `DRW_draw_depth_loop`.
