Wikimedia Bugzilla is closed!

I have an extension running on a parser hook.  Changes to $wgOut are shown when previewing the revision, but not on the actual page.

I have a really easy way to repeat the bug using the ImageMap extension (the bug itself is not in ImageMap)-

-install the ImageMap extension
-modify ImageMap_body.php
   -find the line # Determine whether a "magnify" link is present
   -just before this line, add two lines of code, so the three together are:

global $wgOut;
$wgOut->addMeta ('test', 'test');

# Determine whether a "magnify" link is present


Edit a page with an ImageMap on it.  The meta tag gets added when previewing the page but not on the page itself.
