As a general comment, you cannot leap from empirical data about what
user agents do straight to a conclusion that what the spec says is
"wrong". The spec doesn't need to describe what user agents do, it
needs to describe the behavior that yields the best results with the
web corpus. Particular user agent behaviors today might have neglible
impact on the web corpus compared to the mandates of the spec
tomorrow.
