The issue is in PathCanonicalizeW.
I opened a MR https://gitlab.winehq.org/wine/wine/-/merge_requests/9414 for it.
It is in draft, because of some uncertainty about the special UNC part. The
test do not indicate the need of it, therefore i removed it from the new logic.
Maybe somebody has some hints about it.
