Issue subscription API will not return all participants #26750
Description
Description
If a user commented an issue, then this user will be a participant of this issue, as shown in the issue content page. And the Notifications part of this page, will show a button named "Unsubscribe".
However, if we use the issue subscription API(/repos/{owner}/{repo}/issues/{index}/subscriptions), this user will not be included in the subscription list.
Only if they clicks on the Unsubscribe and then Subscribe, this user will be included in the API.
It seems in the web page, a participant(who create the issue or comment the issue) is treated as a subscriber. But in the API, only the users who subscribe by hand, will be a subscriber.
