System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 528.24

Blender Version
Broken: version: 3.4.1, branch: blender-v3.4-release, commit date: 2022-12-19 17:00, hash: rB55485cb379f7
Worked: 3.3
Caused by da4bd24c3e

Short description of error
In Blender 3.4.1, in Sculpt mode, {Face Sets -> Face Set from Edit Mode Selection} does not correctly create a face set from all the vertices selected in Edit Mode. It works perfectly in Blender 3.0.1

Exact steps for others to reproduce the error

The issue can be easily seen with a triangulated mesh:

add a Subdivision modifier to the cube, and change "Levels Viewport" to "2"
Apply the Subdivision modifier
add a Triangulate modifier
Apply the Triangulate modifier
in Edit Mode, select all the vertices
in Sculpt mode, in the top menu, select {Face Sets -> Face Set from Edit Mode Selection}
as you can see the Face Set does not include all polygons. In Blender 3.0.1, all the polygons change color, indicating that it works.

The issue can also happen on a mesh with quads:

delete the cube, then add a Monkey
add a Remesh modifier to the cube, and select "Smooth"
Apply the Remesh modifier
in Edit Mode, select all the vertices
in Sculpt mode, in the top menu, select {Face Sets -> Face Set from Edit Mode Selection}
as you can see, some polygons are missing from the Face Set
