Enter part of a username in the reviewers field
RB would autocomplete
Then browser would autocorrect - end up with a wrong username

What is the expected output? What do you see instead?
I saw as above. I would expect, if possible, design the field in such a way

  that Safari does not consider the field for auto correction.

MAC/Safari with Safari's autocorrect turned ON.
