That is the correct behavior, from my understanding. Declaring an
<error-page> is telling the container to "use this page *instead* of what
you would normally do". And, because your "/404.html" page actually
exists, a 200 is the correct status for that.

Why not just remove your <error-page> declaration? Then, Tomcat will
return a "real" 404 status?
