When using Dev-tools' Coverage tab, I can see the ratios of used and unused code for a page, with a useful diff highlighting functions that were used and functions that were not. This works with both JavaScript in separate .js files and with JavaScript that has been inlined into my index.html.
The site is built with Gatsby, using Styled-components, which means that during the build, its styles are inlined into the index.html within a <style></style> tag. However DevTools doesn't show any coverage for those styles.
Is there any way to display coverage for styles that are inlined in html?
