We often use inline styles for things like background-images. This is because the image URL is often defined in a meta field. Easier than generating CSS.
For those use cases, WP Stack CDN does not convert the URLs to CDN URLs.
By removing the equal sign from the RegEx pattern, the pattern works properly with these types of URLs. This is obviously a bit less specific, but it's difficult for me to imagine a scenario where this breaks something.
Edit: I pushed an additional commit that adds SVG to the valid extensions.
