Nested color modes

[herrethan]

Say you want to show a small portion of your site in dark mode while in light mode. Because nested ThemeProviders will always inherit the root colorMode, doing this becomes tricky. Some discussion on that here.

However, digging around in the source code I found that NestedColorModeProvider creates a helper class that allows this.

// ... light themed stuff
<div className="theme-ui-dark">
  <ThemeProvider theme={{}}>
    {/* dark themed stuff */}
  </ThemeProvider>
</div>

My question is, is this safe to use? Since it's not documented the concern is how long this might be supported.
