Toolbar button "Restart Kernel and Run All Code..." has no icon

[jitseniesen]

Describe the bug
Toolbar button "Restart Kernel and Run All Code..." has no icon

To Reproduce
Steps to reproduce the behavior:

1. Download source for version 7.0.0a14 (current HEAD)
2. Create development environment following the instructions in CONTRIBUTING.md
3. Start Jupyter Notebook and create a new notebook

Expected behavior
The text on the button looks out of place, it should probably be an icon (or perhaps the button should not be in the toolbar at all).

Screenshots

Desktop (please complete the following information):

• OS: Linux Debian
• Browser: Firefox
• Version: 102.8.0esr

Additional context
The issue may well be in how I follow the instructions in CONTRIBUTING.md (though they seem pretty clear) or the instructions themselves. I have very little JavaScript experience and the build process still holds many mysteries for me.

Thanks @jitseniesen for the report.

This will likely be fixed by #6757, which should include the fix that landed upstream in JupyterLab: jupyterlab/jupyterlab#14000

[jitseniesen]

Thanks @jtpio for your quick reply and fix. You probably don't need this, but I can confirm that the latest release fixes the issue.

More broadly, thanks very much to everybody concerned for your work on Jupyter Notebook 7. I am trying to see whether it can be integrated in Spyder. It looks much better than my previous attempt, that was based on the example-notebook distributed with Jupyter Lab.
