There is a case when an autoconfirmed user moved a page ("H2") to an existing redirect page ("H2 (manga)"), the redirect page is logged as being deleted. Is this behavior intended or is this a bug?

• As reported to one of idwiki admin (Bonaditya) here: https://id.wikipedia.org/w/index.php?title=Pembicaraan_Pengguna:Bonaditya&diff=11820427&oldid=11819972

P.S. The tag "Rang [1.0.1]" is attached to that log. I'm not sure why it got there, but this OAuth application is written by me, hosted at Tool Labs, and is intended for helping image deletions in idwiki (mainly used by me only, and I don't advertise it to anyone; so it's unlikely that anyone else uses this application). This may or may not be related to the case above.
