linux_env - FileSystem::resolve_path - wrong resolutions with symbolic link

[Sh3idan]

My architecture:

file_sb/
├── home
│   └── user
│       └── bin.elf
└── proc
    ├── 1000
    │   └── exe -> /home/bla/[TRUNCATED]/file_sb/home/user/bin.elf
    └── self -> 1000

The function FileSystem::resolve_path returns a wrong path with a symbolic link.

If the target is an absolute path and already a link in the sandbox, resolve_path returns a double sandboxed link. See below:
