'It's' autocorrects to 'it'd' every time. Why can't it learn this behaviour?

[WPCentral Question]

Autocorrect is cool. But if it automatically correct it's to it'd one more time I'm going to lose it!

I seem to only be able to turn the function on or off. Isn't there some way of the system learning this behaviour?!

In settings, go to keyboard and tap advanced button, then tap the "reset suggestions" button. It's (it'd?) possible that, at some point, AutoCorrect's dictionary learned bad behavior...
