if file was removed, file-history-trigger dropdown shows "dead link"

https://bitbucket.org/redcarpetup/desktop-ux/src/7babeeee6860ec9fa23c370a9a8451f61dd6d186/api/migrations/versions/3fc683355007_.py?at=recon_paid&fileviewer=file-view-default\\
this file exists.
However, this file gets removed in commit e1ba31c2747690e179de6ba08694c436ee6d75d2

I choose this commit in filehistory dropdown.

https://bitbucket.org/redcarpetup/desktop-ux/src/e1ba31c2747690e179de6ba08694c436ee6d75d2/api/migrations/versions/3fc683355007_.py?at=recon_paid this is a 404 page "dead link"

What should happen is that in case of deadlink - it should go to changeset https://bitbucket.org/redcarpetup/desktop-ux/commits/e1ba31c2747690e179de6ba08694c436ee6d75d2?at=recon_paid and DISPLAY a MESSAGE saying that file was removed.
