System Information
Operating system: MacOS Moterey 12.3
Graphics card: Intel HD Graphics 515 1536 MB

Blender Version
Broken: 3.1.0 (Release) c77597cd0e master
Worked: ?

When I use an animated Image Sequence as Texture for Particle Density the particles don't behave right, when I click "Refresh" on the Texture in one frame particles are being created but when I go frame by frame (or bake) no particles are being generated. The image sequence contains data from "wetpaint" created with Dynamic Paint, I verified that the images have black background and white / grey blobs for density.

Note: Philipp Oeser (lichtwerk) pointed out

Animating density is a limitation of the current/old particle system.
This dates back to #28212: Bad update on sequence texture for particles and has always been a TODO on the old system #55362: Blender development todo list -- Tools (migrated from wiki)

and

New Geometry Nodes / Particle Nodes will handle this at some point.
