Where did the OP say anything about this issue being caused by SSL?
In order to determine the solution one has to first determine the cause of the problem, n'est-ce pas ?
Others have indicated they are unable to reproduce the problem, which, one would think would have been reproduced and reproducible if the cause were SSL.
I just double checked. Nothing special, it work without issues on my cPanel/https with a commodo certificate.
The things you describe have nothing to do with the editor, which would have needed an addon or core file edits as vb3.8.x does not support WYSIWYG in Chrome, I think you may be confusing that the advanced editor shows but it does not have the WYSIWYG functionality that you would get in IE or FF.
