I'm seeing erratic gaps, in what appears within the cross-wiki notifications.
E.g.
At Eswiki, the items for "mediawiki" and "testwiki" are blank (missing/empty).
At Frwiki, the "Norwegian" section is blank
At Dewiki, the "testwiki" and "Goan Konkani" sections are blank.
It is consistent if I reload the page.
