When looking on a question that was migrated to your site, you can follow the migration notice to the source site. You will see the revision history there (the migration notice under this question migrates to here for example).
The problem is that there is no way to go back to the original question on the source site (UX in this case). The link correctly points to the source site, but it automatically navigates to the target site on clicking the link. I guess adding a
?noredirect=1 to the URL will do.
Can this be implemented please?
