Renaming a page does not update links in other wikis

• Create a subwiki, create a page "foo" in that subwiki
• Go in the main wiki, create a wiki-link to "foo"
• Go to "foo" and rename it to "bar"

Expected behavior: ALL wiki links to "foo" will be updated
Actual behavior: The wiki link in the subwiki is broken.

This defeats the purpose of using a wiki link (could just use a URL link instead)
The rename page actually indicates this:

Update the target of 0 incoming links to this page and preserve the target of relative outgoing links from this page in the new location

The behavior is identically for links in other subwikis, or if the renamed page resides in the main wiki and is linked from the subwikis.

The wiki syntax in the subwiki is:

[[foo>>doc:subwikiname:foo.WebHome]]

The behavior is identical when renaming a terminal page
