Unable to zone into Molten Core via window

I was quite surprised when I was unable to find this issue reported, but you should be able to zone into Molten Core via the window next to Lothos Riftwalker. When I attempted this, I jumped through the hole and died in the lava without so much as a failed loading screen. 

I have three cites for the window phenomenon. First, you're actually still able to zone into MC this way on live, retail servers. Second, according to wowwiki: "Jumping in the lava outside the window works just the same as talking to him [Lothos Riftwalker]" (http://www.wowwiki.com/Lothos_Riftwaker). And third, the song "We're MC raiders" actually refrences this phenomenon: "Talk to the quest guy and jump through the hole" (http://www.leoslyrics.com/myndflame/mc-raiders-lyrics/ and https://www.youtube.com/watch?v=AjmJCy1ksYY).

I also realize this isn't a huge issue, but I really hope these kind of issues can be fixed. These little things are really what makes it feel like we're truly playing "vanilla" WoW.
