If we set grid-template-rows to "repeat(1, [] 10px)", and then read the specified value, what should the result be? (All browsers give "10px" as the computed value.)

• "repeat(1, [] 10px)" - Blink
• "repeat(1, 10px)" - Firefox
• "[] 10px" - Safari
• "10px" Edge 18

Edge 18 only "expands" repeat(1, ...), while Safari expands any repeat(n, ...) in the specified value. (Blink, Firefox and Safari expand repeat(n, ...) in computed values.)
