To reproduce:

1. Set $wgMaxRedirects to something large (e.g. 10)
2. Create a chain of redirects, Redir5 → Redir4 → Redir3 → Redir2 → Redir1 → Target. Probably easiest to do so in reverse order.
3. Call Revision::newFromTitle( Title::newFromText( 'Redir5' ) )->getContent()->getRedirectChain(), or just observe the results rendered for index.php?title=Redir5&redirect=no

Expected result:

There will be 5 entries in the chain: Redir4, Redir3, Redir2, Redir1, and Target.

Actual result:

There are two entries in the chain: Redir4 and Target

Analysis:

WikiPage::getRedirectTarget is the equivalent of Content::getUltimateRedirectTarget, not Content::getRedirectTarget.
