Debugger in Pycharm Jupyter does not work properly when I stop debug and resume

Hi,

When I use Jupyter in Pyhcarm, they support debugging function. In particular, I can do debug cell by cell using Alt + Shift + Enter.

However, I am having a difficulty in using this function. Once I enter in a debug mode using Alt + Shift + Enter keys, it works and it stops at the break point I set.

But, when I click 'stop' debug, it behaves weirdly. After I click stop button and click again resume button, it does not work and in the variable windows, there is a message 'Waiting for connection...'

If it happens, I need to restart pycharm. Restart Jupyter server is not enough. Am I only one who is having this problem?

Basically, right now I cannot use good debugging tool provided in Pycharm.

Since it is not easy to explain in words, please see the video I uploaded in the following link.
