There seems to be a problem with creating new bookmarks. I'm nesting the bookmarks as I create them in order to keep myself organized, considering this PDF is almost 800 pages long. I'm finding that if I nest my most-recently-created bookmark under another one, all future bookmarks I create are also nested under the same bookmark.

However, once I wish to move one of these newly-created bookmarks to the root level, that is to un-nest them, the only way I can do so is to move them to the top of the list. Even if I try to un-nest them via the same movement method I see in YouTube video ID tCqXOaNC_Zg , the bookmark being dragged is still nested anytime I drag it to the bottom of the list, even if the line indicating where I'm moving the bookmark to is longer, indicating it will be at the root level. This erroneous behavior persists when dragging a bookmark to any other location other than the very top of the list.

I believe this is a UI bug because the functionality works, just as long as it's specifically at the top of the list and nowhere else.
