Keyboard shortcuts broken after following internal link

[homeworkace]

Latest stable version, latest stable Firefox, Python 3.11. All keyboard shortcuts and most other mouse functions are broken. Cells cannot be run by keyboard or mouse. Attempting to duplicate or insert cells create empty ones somewhere unrelated. Attempting to delete these empty cells results in other cells being deleted instead. Resolved with reload.

To reproduce:

1. Create markdown cell A as such:

This [word](#link) leads to cell B.

2. Create markdown cell B as such:

<a name = 'link'></a>I am cell B.

3. Ctrl + Enter both cells.
4. Double-click on "word" in cell A.

Thank you @homeworkace for opening this issue. Could you share which version of Notebook you are using? Do you have any enabled browser extensions that might interfere with content? Also, is this issue present with other browsers?

Hi @homeworkace just following up with you, would you be able to provide the information requested above?

Sorry for the inactivity, I'd posted this issue while I was attending to my coursework.

pip freeze shows that I'm using jupyter==1.0.0 and notebook==7.0.6.

I have extensions in Firefox but I don't believe they interfere with the notebook's operation.

• Adblock Plus does not block any elements.
• Honey has no integration with Jupyter.
• Dark Mode is turned off.
• There are no Tampermonkey scripts active on the notebook URL.
• My VPN is not turned on.

I will test this in another browser and in another computer today or tomorrow, and will check back again with the results.

Edit: I closed the issue on accident. At the moment I'm still able to reproduce the bug in my current setup by following the steps above.

This is on a clean Firefox instance launched with Selenium. After following the link (see URL bar), I'm unable to run the cell in the middle:

On Chrome or Edge this bug does not happen. Using Python 3.12 to launch Jupyter (and using the same instance of Python as the kernel) I get the same results.

Thanks for your reply @homeworkace! I was just able to reproduce this in the latest Firefox standard release, 121.0.1, as well. If I save from the File menu and refresh the page, the commands are back. Below is the output I am seeing in the console. The error message was similar to that reported in jupyterlab/jupyterlab#7412 note: this issue is not present for me in JupyterLab itself.
