Issue link created and deleted context parameters

Hey everyone,

as noted in the documentation for Jira webhooks, issuelink_created and issuelink_deleted should support {}, {project.key}, {issue.key}, {} context parameters. However, that doesn’t work.

I’ve tried registering the following webhook (through atlassian-connect.json)

        "event": "issuelink_created",
        "url": "/event/link/created/{issue.key}"

I’ve also tried adding it as a query parameter like "url": "/event/link/created?issueKey={issue.key}"
With both URLs I get undefined as the issue key. Same goes for issuelink_deleted.

I’ve also found this ticket on ecosystem, but it’s been reported in 2018 so I don’t know if it’s still valid. I find it kind of hard to believe that such a trivial bug has gone unfixed for so long.

Basically, I’d like to know if this is a bug in the documentation or a bug in those webhooks. There is a workaround for my use case, but I’d rather have the info readily available without making additional API requests.
