Subject: [PATCH] Fixing #401

Resolving regression caused by #393, and re-introduced original
resize handler method used by @petergood -- placing it behind
lodash .debounce should appease @pitaj's concerns, but I frankly
see no other way to have this feature but also fix cases where
the header is not at the top of the page.
