Vscode-jupyter: Saving plotly graphs as png fails

[DonJayamanne]

The following error is logged in the console window
Uncaught TypeError: elem.className.includes is not a function

[rchiodo]

Fixing this does not fix the graph though. I tried fixing this issue just to see and it had no impact on the plotly link.

@DonJayamanne I'm not sure on the validation here. I don't see an associated PR. Rich moved this to validate, but you had it assigned. Is this plotly only?

[DonJayamanne]

Oops

[DonJayamanne]

This is the PR https://github.com/microsoft/vscode-python/pull/9234
And yes it only applies to plotly.

So, please test saving plotly

[DonJayamanne]

We had to introduce some other fixes. There were a few issues in this space that prevented saving of graphs. This addresses the one with plotly & others (both @rchiodo and I added fixes).

Validated saving a plotly plot as png. Also adding plotly to the manual test file that CTI uses.
