* computed line-height. This calc therefore removes half of the difference
* between the two from the height of the element. This has the result of
* spacing the top of a capital letter from its container similarly to how a
* border or background would be spaced.

* NOTE: This emulates the `text-box-trim` property (bug 1816038). */
