'undefined' is not an object (evaluating '$placeholder.slideUp')
Works for me. Can you please provide more details?
I guess the bug is about http://en.wikipedia.org/wiki/Wikipedia:Village_pump_%28technical%29#watching_star_is_out_of_order_for_an_article The bug reporter linked the bug from there. My testing indicates it's a problem with ogg files at enwiki.
Seems there are two errors: On pages with TMH loaded, you also get: [object Object]' is not a constructor (evaluating 'new mw.Api()') mediawiki.page.watch.ajax.js:127 https://en.wikipedia.org/wiki/Tommy_(film)?debug=true
