`<textarea>` and `DOMParser` are lossy with `\r` character

[xBZZZZ]

var t=document.createElement('textarea');
t.value='\r\n';
console.log(t.value.length);//logs 1

'\r\n' → '\n' '\r' → '\n' ~this is bad because doing nothing and pressing back in many dialogs can actually change stuff!~

also DOMParser:

console.log(new DOMParser().parseFromString('<x>\r\n</x>','application/xml').documentElement.textContent.length);//logs 1

but

console.log(new DOMParser().parseFromString('<x>&#13;&#10;</x>','application/xml').documentElement.textContent.length);//logs 2
