Copybuttons appear on a new line at the bottom of a cell instead of the top right corner

Describe the bug

Copybuttons appear on a new line at the bottom of a cell instead of the top right corner:

I don't know if it is related to the sphinx_rtd_theme.

Also, when I followed the docs to find some info on how to customize the CSS, in this section the following link lead nowhere:
https://github.com/ExecutableBookProject/sphinx-copybutton/blob/master/_static/copybutton.css

Environment

• Python 3.7.6
• notebook: 6.0.3
• sphinx_rtd_theme: 0.5.0
• Operating System: Ubuntu 20.04

hmmm - could this be related to some of the SVG changes that @pradyunsg made to the copy icons? This used to show up fine on RTD I believe.

And thanks for pointing out the broken link, fixed now@!

I tried the css suggestions in #69 but that did not help

Please read this section: https://docs.readthedocs.io/en/stable/guides/adding-custom-css.html#how-to-add-custom-css-or-javascript-to-sphinx-documentation

Please check your project for anything that looks like this:

html_context = {
    'css_files': [ '_static/my_custom_file.css' ]  ## DO NOT DO THIS, RTDs!
}

Please see if correcting this discrepancy resolves your usage issue. Use of html_context like this is overriding and replacing the internal data model, so any extensions that contributed via app.add_css_file() API have their CSS file contributions lost.

This can be confirmed if you check the output HTML for the lack of copybutton.css that is contributed by this extension at https://github.com/executablebooks/sphinx-copybutton/blob/master/sphinx_copybutton/__init__.py#L92
