Summary0000523: body height ignored and scrolling not working properly
DescriptionThe test case sets body height to 100px but it actually expands to fill the viewport.

When the blue-bordered div is clipped scroll bar is displayed as expected but it fails to work as expected most of the the time.

At first, dragging the scroll bar does nothing. By some combination of key presses and mouse clicks it appears that the scroll bar begins to function but it doesn't always do what you expect.

Sometimes its OK, but other times it scrolls the opposite way to the expected direction. This appears to be because the hand pointer is displayed and despite it being over the scroll bar, its being interpreted as over the document content.

Clicking in the space above/below the scroll bar doesn't always do what is expected either, but it does seem to change the behaviour so that sometimes scrolling works OK. This is quite weird and tricky to give precise instructions to reproduce consistent symptoms.

Current master of NetSurf gets the box clipping wrong compared to other browsers (chrome and ff).

If the ns window is resized to clip the blue box scrollbars appear, vertical works but horizontal goes badly wrong, starting operation inverted and then corrupting more state.

We appear to be corrupting heap somewhere!
