Importing files does not account for wxs location

When the wxs resides on a different drive (D:\ for instance) and you import files using import folder, import file, or the wizard import folder. The files imported have a source path without a drive letter I.e. "\tmp\folder\file.name". The MSI will not compile this way. Expected behavior is for it to use the full path I.e. "c:\tmp\folder\file.name".
