Short description of error

The particle system is not properly utilizing the weights that are generated dynamically via the dynamic paint or weight proximity modifiers. The regrow option does not help either.

We already have a report for this, see #77219 (Dynamic vertex groups (Dynamic Paint, Weight Proximity modifier, Geometry Nodes, ...) do not update density of particles in viewport display), will merge reports
