html.elements.datalist - Reports working for Safari, the textual type and date and time type examples do not work

What type of issue is this?

Incorrect support data (example: BrowserX says "86" but support was added in "40")

What information was incorrect, unhelpful, or incomplete?

Datalist is supposed to work in Safari on macOS, but none of the examples actually work. I.e. no autocomplete dropdown opens, the datalist has no effect. An arrow does appear in the input field, but clicking it has no effect.

What browsers does this problem apply to, if applicable?

Safari

What did you expect to see?

In the first example under "Try it", when I type "C" I expect it to suggest "Chocolate" and "Coconut" in a dropdown under the input field. I also expect the list of suggestions to show when I click the arrow in the input field.

Did you test this? If so, how?

I tested this by trying the examples on https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/datalist in Safari 18.6 (20621.3.11.11.3) and Safari Technology Preview Release 225 (WebKit 20623.1.1.1) on macOS 15.6 (24G84).

Can you link to any release notes, bugs, pull requests, or MDN pages related to this?

MDN metadata

Start with the MDN datalist page and its compatibility data for Safari, then inspect the entries covering the textual, date, and time examples. Verify the reported behavior against the cited Safari versions and update the affected support data only if the results confirm the report; done means the data matches tested browser behavior.
