Steps to reproduce the problem:
1. Add a lot of bookmarks, so many that one needs to scroll down the screen to see the last one.  

2. Open bookmarks and scroll down to select a lower/last folder/page

3. Scroll again, select the same folder but change the location of folder on screen i.e. by scrolling slightly less or more this time as illustrated in screenshot. 

What is the expected behavior?
The sub menus of the folder should always be displayed on the either side of the selected folder on the same level. 

What went wrong?
For some reasons, the sub folders are displayed at the very same location as was seen in first attempt, which can be way above or lower than the selected folder, on consequent attempts, making it difficult to navigate to the desired page. 

Did this work before? No

I think its a defect related to bookmark manager, and should be fixed for better browsing experience and easier navigation to desired bookmarks.
