let element = document.createElement("div");
element.style.width = "somethingthatisclearlynotawidth";
console.log(element.hasAttribute("style")); // logs true, should log false.
From https://drafts.csswg.org/cssom/#dom-cssstyledeclaration-setproperty:
> 5. Let component value list be the result of parsing value for property property.
> 6. If component value list is null, then return.
> [...]
> 10. If updated is true, update style attribute for the CSS declaration block.
