Qt handles resize to content on double clicking the separator in the header, by default. However this does not work in FreeCAD. There are no comments on why this was done and is therefore treated as bug instead of feature. Manual testing has been performed after the change and: * Scaling by double clicking separator in header works * Sizes are correctly stored in sheet when resizing to content
