When the "Copy Bible Verses" tool is accessed via the Replace With Passage service, none of the markup is pasted with the text. The text is arranged as per the style, but the markup is all missing. For me it means that the "<sup>" is not coming across and so my verse numbers are no superscript.
Bringing up the CBV tab and using the "copy" or "copy and paste" button works correctly so the bug seems to be limited to the service.
