=================================================================

expandTreeItem is the problem: the element that should appear, never does => TIMEOUT.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/b47fd5bb2acd494c0ad53bede6417b4545407876

commit b47fd5bb2acd494c0ad53bede6417b4545407876
Author: Noel Gordon <noel@chromium.org>
Date: Thu Apr 26 03:55:33 2018

Disable FolderShortcuts/FileManagerBrowserTest.Test DEBUG ASAN

After crrev.com/553147 FolderShortcuts/FileManagerBrowserTest.Test/1
is a persistent TIMEOUT on the DEBUG and ASAN bots, also Test/0 is a
flaky TIMEOUT on DEBUG and ASAN. Disable them on DEBUG and ASAN.

Seems the expandTreeItem querySelector() is the problem: the element
the test expects should appear, never does => TIMEOUT.
