Broken: (example: blender-2.92.0-165b4f85ec23-windows64
Worked: 2.91 alpha?

Short description of error
The Pose and Boundary brushes with cloth simulation as deformation target looks like it changed behavior. No idea if it's a bug or feature.... 🤔

As you can see in the video below (by Pablo Dobarro, posted here: D8578), this is how it used to work:

But now if you try to do the same in 2.92, the behavior is totally different, like if the cloth simulation is more global, and the entire mesh starts moving around, giving you unpredictable results... (I tried to reset the brushes but nothing changed)
