header line drifts off view

[=?utf-8?b?xaB0xJtww6FuIE7Em21lYw==?= <stepnem@xxxxxxxxx>]

The emacs-w3m header line is different from the usual Emacs header line
in that it does not stay visible when scrolling the buffer -- it's just
like a first text line in the buffer, which disappears when scrolling.

I gather the reason is that it's actually _not_ an Emacs header line
(which is used for tab bar in emacs-w3m), but it's very inconvenient --
I find myself wanting to check the current URL very often so I would
very much appreciate if it could stay in view all the time. Is there a
way to get that?

TIA,

Štěpán
