What else does slam earthbound counter besides “dive”?

Maybe I’m tripping, but I was playing Mag the other day, and I’m pretty sure his slam stopped me from dunking on their cloak. Mag ult is technically a mobility so I guess it makes sense? Is this legit? If so, could be a good way to protect my cloak (or Punisher) in the future.

It got me thinking, what other abilities does his slam stop. Thor ult? Strange flight? Peni ult?

On that note, what abilities would you think it should stop, but doesn’t? I see a lot of spideys still swing away, or magiks still portal away. Does it not stop them or are they just making their way out of the effect field?
