Clarify the standardized behavior of appearance: none;
Motivation
Some people misinterpret the original wording as behavior similar to display: none; or visibility: hidden; when in reality it is more like a css-reset.
Here is some supporting evidence of old defintion causing confusion
The element is rendered following the usual rules of CSS. Replaced elements other than widgets are not affected by this and remain replaced elements. Widgets must not have their native appearance, and instead must have their primitive appearance. See § 7.2.2 Effects of appearance on Decorative Aspects of Elements and § 7.2.3 Effects of appearance on Semantic Aspects of Elements for details.
