Thebelab directive: Code highlighting not working properly?

When using the Thebelab button to make the code cells executable, I don't seem to be able to have syntax highlighting working properly.

I tried with a dev install (master branch) of jupyter-sphinx, and it seems that data-language is being set to "ipython" here: https://github.com/jupyter/jupyter-sphinx/blob/28468f22ae8fb9d444ee3b11af04542e7427cb3c/jupyter_sphinx/thebelab.py#L23 This seems to be wrong and should be just "python", but even trying "python" locally does not work for me.

Do you have any pointers to how I could fix this? Could this be a Thebelab issue?

On another note, it looks like the font size changes when making the cells executable?

I just realized there was a sphinx-thebe, where they seem to set the language to Python like this: https://github.com/executablebooks/sphinx-thebe/blob/master/sphinx_thebe/init.py#L109-L110

I was able to get sphinx-thebe to work nicely with jupyter-sphinx, I commented on https://github.com/jupyter/jupyter-sphinx/issues/165 as it's going more in the direction of replacing the current thebe extension from jupyter-sphinx
