According to the documentation https://docs.python.org/3/library/pathlib.html#pathlib.Path.resolve
If strict is False, the path is resolved as far as possible and any remainder is appended without checking whether it exists.

The current behavior is not consistent with this, and only appends the first remainder.

For example:
If we have an empty '/tmp' directory
Path('/tmp/foo').resolve() and Path('/tmp/foo/bar').resolve() both result in Path('/tmp/foo') but Path('/tmp/foo/bar').resolve() should result in Path('/tmp/foo/bar')
