I tested this fix with the image from the issue and also verified the fallback script still works correctly.

This will work, but I'd suggest using the wp_calculate_image_srcset filter for this instead so you don't have to rerun a preg_match on the final content. Approving for now since this addresses the issue.

Great suggestion, I will open an issue to follow up with this improvement.

Otherwise I was goin to suggest that webp_uploads_update_image_references() would do well to incorporate WP_HTML_Tag_Processor. But I guess the function would go away entirely.
