LibWeb: Don't class mousewheel as handled if scroll offset isn't updated

Browse source 
Before this change, you could only scroll the current hovered scroll
container, even if it was at the beginning or end and thus having no
effect.

Now, if it doesn't update, it will not be classed as handled and will
move onto the next scroll container.
