The issue is that NetSurf's core has to render any frame

standard desktop furniture.
It's been a long time, but (again IIRC) I'm fairly sure that
I
concluded when I looked at this that the only way to get "standard"
scrollbars would be to replicate the Wimp's rendering of the component
bits within NetSurf's RISC OS front-end -- which, aside from being
relatively complex, also took us into areas best described as "sparsely
documented" and hence fragile if the OS developers change the way
things work.
I just had a quick peek inside the RISC OS Wikipedia page. There is no
FRAME or IFRAME but it has the extra scrollbar. Its stylesheet defines
the BODY with 'overflow-y:scroll'. Any browser with window furniture
already in place should have that set on BODY by default, shouldn't it,
and ignore if it's set there again? Just a thought.
NetSurf also seems to ignore the principle of what overflow means (I.e.
'*if* the content overflows, do this') though that's less crucial.
<html><head><title>Test overflow-y:scroll</title></head>
<body style="overflow-y:scroll">
Hello World <br>
Hello World <br>
Hello World <br>
</body></html>
Unfortunately, it is also an inherited property as this short HTML page
demonstrates! Use it with care please Jimmy!
