layout: Change the request-mode along with the orientation

Browse Source 
When changing the orientation of a FlowLayout, the associated
container should also change its request mode. A horizontally
flowing layout has a height depending on the width, since it
will reflow vertically; similarly, a vertically reflowing layout
will have a width depending on the height.
