Feel free to fix it... :-)

The issue is that NetSurf's core has to render any frame furniture when a
page requests it be drawn, and whilst it defers this to the GUI (IIRC), it's
fairly non-trivial for the RISC OS front-end to use the 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.
