Setting FlowDirection = RightToLeft on MetroWindow kills Maximize functionaliy

[jonyadamit]

When FlowDirection is set to RightToLeft, while BorderlessWindowBehavior is applied, the following happens when the window is maximized:

• Window appears the same size, only aligned to the top left
• Window becomes 'unclickable'. Every click brings background windows to the front. If there are not background windows, the click interacts with the desktop.
• The window is completely unusable and there is no way to close or restore it.
