A fraction for a window border position remains a fraction (of the frame
size) if it is an inherent result of resizing the frame. If the user
adjusts individual window borders, however, their new position is an
integer since it is not an implicit result of frame resizing.
In a nutshell: whatever position is manipulated _directly_ is made an
integer at the time of the manipulation. Window borders that are only
repositioned as an implicit (proportionate) result of some resizing
operation, do the bookkeeping of their position as a fraction that
corresponds to the resized ratios.

Resizing manually manipulates the outer window edges directly. So they
are candidates for integral representations as a result of the
manipulation.
