code-fullscreen is not compatible with dark-mode yet

[hdocmsu]

Hi @shafayetShafee, thanks for developing the useful extension. I am trying to use it for the website with both light and dark mode and it works nicely for light mode where the fullscreen-background is bright and the text is dark. However, when I turn the website to the dark mode, the fullscreen-background is still bright and the text is bright so they do not go well together. Is there a way that you can update the extension such that when the website is changed to darkmode, the background of the code-fullscreen is also automatically change to dark-gray/black so that the code shows well? Thanks

Here is an example of how it looks with darkmode.
