Snapshot HTML produces invalid html file with Jupyter Notebook version 7

[deankarlen]

• K3D version: 2.15.3
• Python version: 2.15.3
• Operating System: MS Windows 11

Description

The Snapshot HTML produces an invalid file when using Jupyter Notebook Version: 7.1.1

The same code produces a valid file when using Jupyter Notebook Version: 6.5.4 (significantly larger file size).

Example files:

Run with Jupyter Notebook Version 7.1.1 and click on Snapshot HTML control. File that is produced does not work with Firefox or MS Edge browsers. (File produced with earlier version of Jupyter Notebook is fine).

I've attached the files produced from notebook 6.5.4 and 7.1.1:
