System messages on hover for search types ("content pages", "files", etc..) seem to be somewhat broken.
Fixed in r49935.
Define "broken"? Unless someone's putting something that doesn't belong into the message, I don't see how this would come up. Explain?
My interpretation was that the entities were shown literally. Those came from $wgLang->commaList().
Namespace names don't contain character reference entities.
$wgLang->commaList() uses comma-separator message, which hash   in most languages to combat trailing whitespace removal. Fixed in another way by Tim in r51453.
