Theme doesn't apply very well to React DevTools tab

[luke-denton-aligent]

I've just installed the React Developer Tools extension, which adds a React tab in DevTools. It appears that the tab doesn't pick up the font size, but does pick up all the other theming information (colours etc)

I don't even use React, I just happen to be checking another site to see if it is using the library, and noticed the issue, so thought you might like to know.

Thanks
