Safari 12, Safari Technological Preview and Epiphany Technological Preview (Epiphany Technological Preview 3.31.90-45-ga15d70306 with WebKitGTK 2.23.3) fail these 4 sub-tests.
In each of these 4 sub-tests, the percentage should precede the dimensions.
"
To serialize a summation:
Sort the terms in the following order:
The number, if present
The percentage, if present
The dimensions, ordered by their units ASCII case-insensitive alphabetically
(...)
