It is also not clear that Dumbledore can see through the cloak. 
Perhaps he saw only  Harry's reflection in the Mirror of Erised. An 
intriguing possibility is that Snape was there, saw who killed 
Sirius, but can't reveal it without blowing his cover.

Berit replies:

I think you're right that we don't have hard canon evidence 
Dumbledore really can *see* through invisibility cloaks, but it's 
quite likely he can. It's not only the incident of the Mirror of 
Erised; Dumbledore was also very much aware of Harry and Ron's 
presence in Hagrid's hut when Fudge came to arrest Hagrid in CoS; 
Harry and Ron were standing quietly in a corner, covered with the 
cloak. Neither Fudge nor Lucius Malfoy (who also paid a visit) saw 
the boys. But before he leaves, Dumbledore says something that is 
clearly meant for Harry's ears and not for any of the grown-ups 
present:

"'However,' said Dumbledore, speaking very slowly and clearly, so 
that none of them could miss a word, 'you'll find that I will only 
truly have left this school when none here are loyal to me. You will 
also find that help will always be given at Hogwarts to those who 
asks for it.'
For a second, Harry was almost sure Dumbledore's eyes flickered 
towards the corner where he and Ron stood hidden." (CoS p. 195 UK 
Edition)

So, this suggests quite strongly DD knew they were there. If it's 
only a "feeling" he gets, some sort of radar, or if his eyesight 
physically is able to penetrate the fabric of the cloak we don't 
know, but from the "flickering of his eyes" it's safe to assume he 
can see through invisibility cloaks.
