Bookmark is dragging when clicked once

[dmitry]

Hi everyone!
I have just upgraded my 16.04 Ubuntu to 18.04.1 Ubuntu.
I have added bookmarks in the left panel of my Nautilus that I frequently use for my work, but when I left-click once on any of them the bookmark is dragging together with the mouse cursor that is changed to a "hand" with "+".
Destination of the bookmark is also opening.
But I have to click ESC on the keyboard to get rid of the dragging feature OR I have to click again on the left panel to return the bookmark on its place.
It is quite annoying...
Thank you for any help!

I have found that on GNOME Ubuntu 18.04 it is easier to use this method when such bugs happen:
1. Click ALT + F2.
2. Type "r" in the pop-up window.
3. Press ENTER.
Desktop environment will reboot and most probably the problem will disappear.

I have also experienced this issue on my Ubuntu 20.04 Installation, and the only method to resolve is to restart the computer. The method stated by dmitry does not work for me.
