System Information
Operating system: Windows-10-10.0.19045-SP0 64 Bits
Graphics card: NVIDIA GeForce GTX 950M/PCIe/SSE2 NVIDIA Corporation 4.6.0 NVIDIA 512.15

Blender Version
Broken: version: 4.2.2 LTS Release Candidate, branch: blender-v4.2-release, commit date: 2024-09-12 12:38, hash: 252cc7839f14
Broken: 2.93.18, 3.3.21, 3.6.12
Worked: 2.83.20

Short description of error
mesh boundary incorrectly calculates edges in sculpt mode with multiresolution modifier

Exact steps for others to reproduce the error
Use any surface. Add a multiresolution modifier and enable mesh boundary. Where the original model has edges, sculpting doesn't work.

Reported behavior seems to exist in 2.93, 3.3 LTS, 3.6 LTS, but behaves as expected in 2.8
