api.Clipboard.write - Example does not work in Safari

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?

The compatibility table says writing the clipboard would work in Safari. But the sample that copies the blue rectangle to the clipboard fails in Safari. Nothing happens when I click the rectangle. It works in Chrome and Firefox.

What browsers does this problem apply to, if applicable?

Safari

What did you expect to see?

A text showing "Copied", and the blue rectangle appearing in the box below when pasted.

Did you test this? If so, how?

Yes, in Chrome, Firefox and Safari (under maxOS Sequoia 15.2)

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

MDN metadata

Start with the api.Clipboard.write compatibility entry linked from the MDN URL and reproduce the reported sample in Safari, comparing it with Chrome and Firefox. Determine whether the compatibility data or the example behavior is incorrect, then update the relevant data so the table matches the tested result and verify the reported copy and paste behavior.
