In Bug 1349896 - Implement devtools.panels.themeName (landed in Firefox 55), we have added the devtools.panels.themeName property (which is also supported on Chrome) and the devtools.panels.onThemeChanged event (which does not exist on Chrome) to the WebExtensions devtools APIs.
This API will be available to the WebExtensions DevTools Addons that want to customize their UIs based on the currently enabled DevTools theme.
