Steps to reproduce the problem:
1. Create directories "originals" & "copies" in the root directory using the Google Drive web interface.
2. Put some files in the "originals" directory.
3. In the Google Drive web interface, select the "originals" directory, and press "Shift + Z". Select "Add to" (NOT "Move to"), and put the "originals" directory inside the "copies" directory.

i.e. The Google Drive equivalent of a Symlink of a directory etc.

What is the expected behavior?
Using the ChromeOS files app, you should now see the "Originals" directory in it's old location (e.g.  "Google Drive -> My Drive") AND under the "copies" directory in the ChromeOS files application under "Google Drive -> My Drive -> copies".

What went wrong?
When viewed with the native ChromeOS files app, the directory (and/or files) do not show up. They should be visible.
File system view via the files app is inconsistent with the web interface view.

Note: It performs correctly on the Google Drive web interface. i.e. Like a Unix symlink.

Note: "Move to" works as expected.
