Test case for line-height: 1lh

A declaration of `line-height: 1lh` should technically imposed the line height of the parent element. 

However, when the element's font size is fixed up to respect the user's preferred minimum font size, its line height is (unexpectedly) increased proportionally, possibly related to: https://bugs.webkit.org/show_bug.cgi?id=174406

The attached test case contains two paragraphs each with a declaration of `line-height: 1lh`. When the user configures their minimum font size to 24px from Safari's settings, the line height of the two <p> elements gets out of sync with the parent's line height, and with each other.
