What it does
fixes #13223
This fixes a few issues with the notebook output rendering and the associated webview.
Also improves performance a bit because the webview is reused when the cell is executed again.
How to test
Create a new notebook or take an existing one. Just try to execute some cells.
Also see #13223 for specific test code. This should now be rendered correctly without extra outputs.
