I too read it as noise. This happens to me very often these days , don't know if it's part of some cognitive decline :P
EDIT:
Another such HN headline misreading was when I read "The contribution of Cheese to western civilization" as "The contribution of Chinese to western civilization" .
Nope, I did "virtual noise, huh? Interesting. Wait, wasn't there an article the other day that added a nose to get rid of motion sickness as well? Hmm, does it actually say noise? Nope :/"
I'm not sure that is different. The perception part is still filling in what fits based on context. It takes your consciousness to tell the perception 'read again while suppressing spellcheck'.
Have you ever read the paragraph where every word is misspelled but people tend to be able to read with very little reduction in speed?
