Confluence's wiki markup for shortcuts cannot deal with an `@` sign which is itself in the URL.

For example, when creating a shortcut to google and entering a search term, in the shortcut, containing an '@' symbol, the intended result is not achieved.

Key:
google

Expanded Value:
google.com

[support@atlassian.com@google.com], which would ostensibly search for support@atlassian.com through Google, won't work.
