os.root("C:/") fails in Windows

[philwalk]

The following script illustrates the problem:'

#!/usr/bin/env -S scala-cli shebang

//> using scala "3.3.1"
//> using lib "com.lihaoyi::os-lib::0.9.2"

import os._

val root1 = os.root("C:\\")
printf("cRoot: %s\n", root1)
val root2 = os.root("C:/")
printf("cRoot: %s\n", root2)

The output:

# /opt/ue/jsrc/oslibRootBug.sc
cRoot: C:\
Exception in thread "main" java.lang.AssertionError: assertion failed: C:/ is not a root path
