Is there a reason this is conditional? And do you really want 1924 if chromeos?

Yes, In Chrome OS, some volumes are mapped to native directories (e.g.
Downloads, USB storages), and in that case we don't need to use externalfile://
scheme URL. For non-native volumes (e.g. Google Drive, MTP, FSP) we access the
files by using externalfile:// URL.

The original function MaybeSetDriveURL replaces the URL for drive volumes, and
keeps the file:// URL for other types of volumes.
