The HTML compat data is missing <input> element compat data.

MDN pages to migrate:

• Web/HTML/Element/input
• Web/HTML/Element/input/color
• Web/HTML/Element/input/date
• Web/HTML/Element/input/datetime-local
• Web/HTML/Element/input/email
• Web/HTML/Element/input/file
• Web/HTML/Element/input/hidden
• Web/HTML/Element/input/month
• Web/HTML/Element/input/number
• Web/HTML/Element/input/radio
• Web/HTML/Element/input/range
• Web/HTML/Element/input/reset
• Web/HTML/Element/input/submit
• Web/HTML/Element/input/tel
• Web/HTML/Element/input/text
• Web/HTML/Element/input/url
• Web/HTML/Element/input/week
• Web/HTML/Element/input/button
• Web/HTML/Element/input/checkbox
• Web/HTML/Element/input/search
• Web/HTML/Element/input/time

The data should be stored at html/elements/input.json and there will be some deeper nesting involved for the various attributes and input types.

• html.elements.input
  • accept
    • mime_type
    • file_extension
    • ...
  • form
  • list
  • ...
  • type
    • email
    • week
    • ...
