html.elements.a.attributionDestination - Missing keys for private click measurement

[ddbeck]

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?

Private click measurement data is incomplete; two keys I'd expect to exist are missing.

What browsers does this problem apply to, if applicable?

No response

What did you expect to see?

I'd expect to see keys for:

• html.elements.a.attributiondestination
• api.HTMLAnchorElement.attributionDestination

with support shown in Safari.

Did you test this? If so, how?

I didn't test it properly (it's a rather complex API), but "attributionDestination" in HTMLAnchorElement.prototype returns true in the current version of Safari. That said, I'd expect the data to be equivalent to the already-recorded attributionsourceid attribute.
