Box with `box-sizing:border-box` causes incorrect width calculation

Reviewed by Alan Baradlay.
Fix width calculation for boxes with `border-box`, `aspect-ratio` and `display:
positioned`
When a box has `box-sizing: border-box` and an aspect ratio set and is
positioned,
the width calculation incorrectly adds the border and padding to the box size.
Since the box uses `border-box`, this border and padding addition is wrong.
This patch fixes the behavior by checking if box has `box-sizing: border-box`
and an aspect ratio before setting the final width value.
