The sidebar bookmarks cannot be unsorted and cannot display the last expanded folder

Description of the issue:

After the several recent updates the Bookmarks in sidebar ALWAYS displays the root folder which makes it very inconvenience for users who has complex structure of bookmark, let alone the force sorting. @jdellasala has previously provided this feedback but no one replies I am afraid. Hope the development team will take this issue seriously.

How can this issue be reproduced?

  1. Open the sidebar
  2. Select Bookmarks
  3. The root bookmark folder is displayed and it is forced to sort

Expected result:

  1. Unsort the bookmark in sidebar or at least give users an option.
  2. Remember the last expanded folder like the old versions do.
