Track size labels currently do not show a value of `auto` when `auto` is implicit. Additionally, we don't want to show computed sizes in these labels as they are 1. additional noise when looking for information and 2. information that should not be a focal point of modern page layout. Children in the grid can still have their computed sizes looked up in the Box Model diagram.
