Mac Technique: Arrange bookmarks of Chrome brower in alphabetical order

When I tried to sort my Mac's Chrome bookmarks in order with this procedure:

Select => Bookmarks => Bookmarks Manager => Organize => Reorder by title

The bookmarks are sorted in order.

However, if I turned off the Chrome app and restarted it. The alphabetical order of bookmarks was gone!

Then I find a solution from:

How do I arrange bookmarks in order? (Google Chrome Help Forum)

I simply:

1. Do this same step as before:

Select  => Bookmarks => Bookmarks Manager => Organize => Reorder by title

2. Cut all the reordered bookmarks and paste them back immediately.

Then the bookmarks are arranged in order even after the restart of the Chrome app!!
