Bookmakrs - not easy saving them by using drag and drop (157 version and a few earlier)

[Usernametaken]

It became harder to save bookmarks by using drag and drop (from tab to menu folders). They behave like a slippery soap. I try to pool down a tab, to save in a menu bar folder, and sub folder (that might be located left or right). I have to drag the link very precisely in the perfect path to the preferred folder. I have to make an attempt few times, because when I want to move the mouse left or right, it just misses the location/folder and the whole folder structure that was rolled down, just roles up within a second or less, and I have to move back again, and again, until I do it very precisely and very, very slow. And I don't suffer from any muscle/movement coordination issue.
In previous versions (maybe before 140 or earlier), this was not like this. The folder structure was more forgiving. This time, with this rounded edges of folders and links, suddenly it's harder, and I need to be more precise like I'm trying to push a thread through a needle.
So, if it could be possible to make the ROLL UP TIME longer... drag and drop feature "sturdier" - if that make seance.  I'll be happy to record a video of what is happening, if it helps? 
Thank you.
