Speaker Notes not showing

Thanks for this plugin. I have used it to create a substantial presentation (on my WAMP) and been discovering how to use the Block editor as well.

One minor issue has been that the speaker notes and time controls did not show. I have tracked this down to them using the default body spec in speaker.css which has color #fff; and corrected it by adding color #000; to .speaker-controls-notes and .speaker-controls-time.

Not sure why the body would be white on dark, and maybe I could just have changed that. I look forward to seeing and using future developments of the plugin.
