Actually apparently Dumbeldore believes that Dementors should be able detect people in an Invisibility cloak, because they sense them through emotion.
Everyone expects invisibility cloaks to not be very good—they usually aren’t. The Deathly Hallow one is described as being fantastically valuable for being a ‘true’ invisibility cloak*, and not merely equivalent to a ‘very strong Disillusionment charm’ and weakening quickly with age (to quote from memory Luna Lovegood’s dad; and speaking of them, we haven’t heard very much from them since the first few chapters).
If Dumbledore expects a ‘true’ Invisibility cloak, then this is basically == expecting Harry.
* Yes, this does raise the question how Dumbledore could apparently see through it to Harry and the Mirror of Erised in book 1. The charitable explanation is that he was bluffing or heard Harry; the uncharitable one is that like Lucas, Rowling only came up with the Deathly Hallows and the ultimate ending late in the game.

That is undeniable. Invisibility cloaks are mentioned in the early books, and no hint whatsoever is given that Harry’s is special. It would have been better if she could have done a real Lucas (or an Eliezer) and edited the earlier references in the earlier books.

I’m not sure which is worse—a single magic gene or midichlorians. But to be honest I might be willing to trade off Ron for Jar Jar.
