Multiple cells selection not working on windows.

I recently started using jupyter notebook on windows 10 in anaconda . Pretty much everything else works as usual, but it wont let me select multiple cells.

I am using chrome 67 but same happened in internet explorer, so I think its browser independent.

None of neither shift click, nor control click nor shift J short cuts do what they are supposed to. They just move focus to the pointed cell, but deselect the old cell. Using command mode doesn't work either. Other shortcuts work just fine.

I am using:
Anaconda 1.8.7
The version of the notebook server is: 5.5.0
Python 3.6.5 |Anaconda, Inc.| (default, Mar 29 2018, 13:32:41) [MSC v.1900 64 bit (AMD64)]

I only installed jupyter on a new environment created in anaconda

Reproduce the issue in Jupyter Notebook 5.5.0 on Windows 10 using Chrome or Internet Explorer, then test shift-click, control-click, and shift-J in command mode. Done means multiple cells remain selected through the documented selection actions while other shortcuts continue to work.
