I am kind of curious to the replace behavior of srcset attribute in img tag.

When I chose Backup mode, and after synchronized, I found that the URL in src attribute is still WordPress URL, but the URLs in srcset attribute are replaced to gcp URLs in img tag

I think all URLs inside img tag should not been changed, because I chose Backup mode.

I tried to read source code and found that srcset urls will be replaced regardless of mode.

I am not sure this is an expected behavior or a bug?
