In `C:\Users\bpb\dev\bugs`, create `dir`, `dir\subdir`, and `link -> dir\subdir`. Then running a simple native test using `CreateFileW` to create a new file `C:\Users\bpb\dev\bugs\link..\file.txt` actually creates `C:\Users\bpb\dev\bugs\file.txt`, which corroborates the conclusion of this PR. The initial version of this PR incorrectly expected that `file.txt` would be `C:\Users\bpb\dev\bugs\dir\file.txt`.
