It is possible for a mesh to change topology across frames but still be detected as not needing a topology update. Until we can make a finer-grained check against the before and after topology, unconditionally ensure it's updated for now. Adds a new test that checks a few frames of changing topology that is similar, but not the same. Pull Request: https://projects.blender.org/blender/blender/pulls/140253
