This is similar to putting a Map inside a Pivot - which is discussed here - http://mine.tuxfamily.org/?p=111 - already mentioned in quite a few questions - https://stackoverflow.com/search?q=mine.tuxfamily.org
In general, the advice seems to be usability based:
As an aside, if you are just using the web browser control for a very small amount of static html (so you don't need any scrolling at all) then you could just remove HitTesting from the web browser.
