m_viewLayoutSize exists in both WebPage and ViewportConfiguration. However, they mean different things (ViewportConfiguration’s m_viewLayoutSize is about the size of the platform view, and WebPage’s m_viewLayoutSize is about special the autosizing/autolayout mode on macOS that’s guarded by SPI).
This makes some existing viewport configuration logic difficult to refactor and fix.
