Given the task URL above is not public, I will copy some relevant info from it.

Task: Make sure copy pasting a username or password (in a login prompt) with a leading or trailing space doesn't cause a problem

This happens, and leads to support issues. Unless we think there is going to be a password with a space, it should be trimmed, or at least a warning given. (ex.: "You have a leading or trailing space")
