While the bug was originally filed for the Java-compositor version of fennec,
the same symptoms also occur in Maple. This patch removes the vbox that browsers
were put in, as it's no longer necessary.
Zooming in caused the right and bottom edges of the page to be clipped. This
was because we would try to scroll to coordinates that, untransformed, would be
invalid. The document has no knowledge of the zoom, and so the scroll position
needs to be forced somehow.
Java compositor accomplished this using a CSS translation transformation, this
accomplishes it by turning off scroll position clamping (a technique that the
Java compositor should also employ, if the patch this relies on passes review).

Realised I made a mistake with the nsIFrameLoaderOwner.clampScrollPosition
patch and I want this to go in as a single commit and not break building of
Maple.
