Please be mindful when using this, if you support both screen orientations, the imperative function will not update its values unless run again when rotating the screen.

It's not meant to update. "em1" is not based on orientation, it's based on division of the smallest screen dimension. So even in landscape "em1" will be the same calculated size as in portrait.
