Pretty much anything you do other than run (and don't get hit) cancels the effect.
Frost Nova + run and invisible does indeed reset the mobs so long as you don't get hit during that 5 seconds until you turn invisible.
Mounting cancels it. Blink will cancel it. Bandaging cancels it. Eating or drinking cancels it.
If you have a DOT on you it will cancel on the first tick of the dot.

This does not share a cooldown with invisibility potions, so you can bust out up to 38 seconds of invisibility if you use one at the last second of the spell.
What would be great here if someone posted a comprehensive guide on the tactics, mechanics and cool stuff you can do with Invisibility. One that is a definitive guide, not with all this arguing about out of combat crap etc and people contradicting each other.
