[@position-fallback] Make sure LayoutObject style is correct

When trying to make room for absolute positioned with position-fallback
the style without animations applied is used. Since TryCalculateOffset
uses a mix of the passed in style and the style retrieved from the
LayoutObject, we need to set the base style on the LayoutObject to make
sure they are in sync.
