I don't understand why my code is timing out.

Also, the test cases that are timing out are different.

I don't understand why.

    puts items in bookmark folders
      1) moves bookmarks from different folders into the target folder
      2) "after each" hook: afterEach for "moves bookmarks from different folders into the target folder"

Gonna close this based on our discussion on #501, but let me know if you're still interested in pursuing it.
