Inconsistent / Incorrect "Missing Value Defaults" for rehype-minify-enumerated-attribute

[karlhorky]

Subject of the feature

Copied from the comments in #36 #36 (comment)

Going through MDN and the HTML spec, found some more inconsistencies / additions:

1. the missing value for ol[type] should be '1'
2. the missing value for ul[type] should be 'circle'
3. the missing value for form[target] should be '_self'
4. [autocomplete]: should this have an array of tagNames? MDN says <input>, <textarea>, <select>, and <form>
5. img[decoding]: missing value default of 'auto'
6. [loading] should be ordered after [keytype] and [kind]
7. [formmethod] should have a missing of null (from the spec: "The formmethod attribute ... has no missing value default."). Maybe also change the comment to update the [method], because it isn't actually 100% synced...
8. [formenctype] should have a missing of null (from the spec: "The formenctype attribute ... has no missing value default."). Maybe also change the comment to update the [enctype], because it isn't actually 100% synced...
9. [formtarget] probably should have a missing of null (couldn't find it in the spec, but seems consistent with the others). Maybe also change the comment to update the [target], because it isn't actually 100% synced...
10. the missing value default for li[type] should maybe be null instead? (from MDN: "This type overrides the one used by its parent <ol> element, if any.")

Problem

I'm trying to gather a list of "missing value defaults" for a new ESLint rule:

jsx-eslint/eslint-plugin-react#2866

Also see #36

Expected behavior

The list should be complete and correct.

Going through this now, I’ll jot some notes down here:

• ul[type] — the default is not circle, the default is based on CSS inheritance
• autoComplete:
  • form[autoComplete] is a simple enum, so I added tagNames: 'form'
  • autoComplete applies to: select, textarea, input[type=hidden,text,search,tel,url,email,password,date,month,week,time,datetime-local,number,range,color]
  • autoComplete does not apply on: input[type=checkbox,radio,file,submit,image,reset,button]
  • on and off are not allowed on input[type=hidden]
  • On input, select, textarea, the default depends on the corresponding form
  • As autoComplete on input, select, textarea are so complex, I instead ignore them here

Thanks! Went through most of these with a browser, to make sure the input and minified result are the same, for the DOM or as the visual result!

Amazing, thanks! 🙌
