Starcraft 2: How to repair a bunker with an scv inside it

Basically, put an scv inside a bunker then right click the bunker. He'll start repairing any damage the bunker has sustained. Do note that this isn't autocast, so once he gets it to full health should the bunker take any additional damage you have to tell him to get back to work.

If I had to guess, I'd say this works because the bunker's right click is kind of like a move function. So telling the bunker to right click itself activates the SCV's repair.

I tried the same thing with a command center and Planetary fortress, but it did not work. I'd assume because the right click for those is a gather resources instead of a general move?

Anyway, just making this video to show off this exploit and garner it enough attention that it gets fixed. I don't think this is an intended ability since it doesn't work on the cc/pf, and it's quite overpowered when combined with early bunker rushes. Bunker rushes were defeated by taking out the repairing scv, but since you can't do that if he is inside the bunker...
