@mehulkaklotar Nice catch! @felixarntz @adamsilverstein Can you please take a look at this and let me know if this is expected behavior and/or something that we should address sooner than later?

@mehulkaklotar Good catch indeed! I can confirm this is missing from our implementation. We should add support for deleting any backed up sources to our webp_uploads_remove_sources_files() function. It needs to cover:

• Delete the sources files for each sizes within _wp_attachment_backup_sizes.
• Delete the sources files from _wp_attachment_backup_sources.
