It would be great if the right column that shows the bookmarks was independently scrollable from the left column that ha the bookmark hierarchy organization. As is, when there is a lot of content in the left column and the user scrolls to the bottom of the left column then the content in the right column also scrolls. This is a problem because the content in the right column is no longer visible because the user has scrolled to the bottom of the left column.

@alexwykoff isn't this dup of #5076 which was done in 0.15.300?
