20 HTML attributes missing in json #25075
Description
What type of issue is this?
Other
What information was incorrect, unhelpful, or incomplete?
I have been working on this table https://potahtml.github.io/namespace-jsx-project/index.html It's a mash-up of frameworks namespace JSX, browser setters (chrome, firefox), vscode html LSP, and MDN
The data from MDN is missing some information:
- Missing deprecations
For example: When reading èlement.json such for style to be https://github.com/mdn/browser-compat-data/blob/main/html/elements/style.json then attribute scoped is missing in the JSON. I can somewhat confirm its deprecated because theres a note here (CTRL+F for "scoped") https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes
The list of attributes I could confirm that are deprecated but missing in $element.json are the following:
// deprecated https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes
'img.HTMLImageElement.intrinsicsize': true,
// deprecated https://developer.mozilla.org/en-US/docs/Web/HTML/Element/col#bgcolor
'col.HTMLTableColElement.bgcolor': true,
// deprecated https://developer.mozilla.org/en-US/docs/Web/HTML/Element/colgroup#bgcolor
'colgroup.HTMLTableColElement.bgcolor': true,
// deprecated https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script#language
'script.HTMLScriptElement.language': true,
// deprecated https://developer.mozilla.org/en-US/docs/Web/HTML/Element/form#accept
'form.HTMLFormElement.accept': true,
// SVG
// deprecated https://developer.mozilla.org/en-US/docs/Web/API/SVGStyleElement
'style.SVGStyleElement.type': true,
// MATHML
// deprecated https://developer.mozilla.org/en-US/docs/Web/MathML/Element/annotation-xml
'annotation-xml.MathMLElement.src': true,
// deprecated https://developer.mozilla.org/en-US/docs/Web/MathML/Element/annotation
'annotation.MathMLElement.src': true,
// deprecated https://developer.mozilla.org/en-US/docs/Web/MathML/Element/ms
'ms.MathMLElement.lquote': true,
'ms.MathMLElement.rquote': true,
// legacy deprecated https://developer.mozilla.org/en-US/docs/Web/MathML/Element/mstyle
'mstyle.MathMLElement.scriptminsize': true,
'mstyle.MathMLElement.scriptsizemultiplier': true,
// deprecated https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes
'style.HTMLStyleElement.scoped': true,
'style.SVGStyleElement.scoped': true,
- Missing information
I couldn't find information about the following attributes, but I am pretty sure these are deprecated/obsolete.
// not found in mdn
'iframe.HTMLIFrameElement.allowtransparency': true,
about the following, I am not that sure any more, but I suppose I have found these are deprecated
'iframe.HTMLIFrameElement.seamless': true,
'object.HTMLObjectElement.typemustmatch': true,
'menu.HTMLMenuElement.label': true,
'menu.HTMLMenuElement.type': true,
- Missing Tags
I couldnt find a $element.json file for the following tags. There are other deprecated tags such frameset.json. So I suppose it would be only consistent to add them, maybe.
'applet',
'basefont',
'bgsound',
'blink',
'listing',
'isindex',
'keygen',
'menuitem',
'multicol',
'nextid',
'noindex',
'spacer',
'content',
'portal',
'image',
'imagee',
'shadow',
- The following have the experimental bit set, but I am not convinced these are still experimental
a.SVGAElement.ping
script.SVGScriptElement.async
script.SVGScriptElement.defer
