Thank you, @tkent-google !

For `textfield` being special on `<input type=search>`, I had identified web content that use this in my previous analysis of httparchive. ([comment above](https://github.com/w3c/csswg-drafts/issues/3024#issuecomment-431339106))

For `menulist-button`, I have tried today to find examples in httparchive where this value is used on elements that are not `select`, and I couldn't find any. (I found various selectors targeting other elements, but upon closer inspection, either there was no such element, or `-webkit-appearance` was overridden by a different style rule, or some other.)

How do we find out where this is needed? Can we try making it an alias to `auto` and see if we get any bug reports, knowing that usage is low and having tried to find things that would break has so far yielded nothing?

`searchfield-cancel-button` is used on a pseudo-element in the UA stylesheet. I've seen examples on the web that set -webkit-appearance to this value on that pseudo-element, but not on other things. I will take another look for cases where it's used on something else.
