async-unsanitized-html-formats-write-read relies on very strange combination of style.

I'm not sure why this test exists, but it doesn't seem robust. Should it be removed? or modified.

it says it expects:

       style="
            color: blue; 
            font-size: medium; 
            font-style: normal; 
            font-variant-ligatures: normal; 
            font-variant-caps: normal; 
            font-weight: 400; 
            letter-spacing: normal; 
            orphans: 2; 
            text-align: start; 
            text-indent: 0px; 
            text-transform: none; 
            widows: 2; 
            word-spacing: 0px; 
            -webkit-text-stroke-width: 0px; 
            white-space: normal; 
            text-decoration-thickness: initial; 
            text-decoration-style: initial; 
            text-decoration-color: initial;
            "

Safari for example sends back

       style="
            color: blue; 
            font-style: normal; 
            font-variant-caps: normal; 
            font-weight: 400; 
            letter-spacing: normal; 
            orphans: auto; 
            text-align: start; 
            text-indent: 0px; 
            text-transform: none; 
            white-space: normal; 
            widows: auto; 
            word-spacing: 0px; 
            -webkit-text-stroke-width: 0px; 
            text-decoration: none;
            "
