Multicursor movement messed up with `foldfix` enabled

[mindgroove]

Describe the bug
When activating multicursors with v selection followed by gb, and then moving vertically with j or k, the multicursors lose their relative vertical positions and merge

To Reproduce
1.Select a pattern with v
2.Type gb to select to instances of pattern followed by esc
3.Try moving vertically with j or k
4.Observe multicursors missalignment

Expected behavior
Multicursors should keep their vertical relative position when moving vertically with j or k
