This has been initially reported at https://ro.wikipedia.org/wiki/Wikipedia:Cafenea#Problema and I was able to reproduce it. Go to any Wikipedia webpage and click the edit link. Expand the special characters section and click on any of the buttons there. On the first click, nothing happens except some kind of scrolling of the page. On subsequent clicks, the char is correctly in the edit box. Apparently it works in older versions. User agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)
Created attachment 9361 [details] Screenshot on ro.wikipedia.org in IE 9 / Windows 7 Works for me on en.wikipedia.org and ro.wikipedia.org in IE 9, Windows 7. Kinda reminds me of bug 31847, the fix for which should have gone live a few days ago.
I've tested it some more, and apparently it only happens when I'm logged out. Perhaps there is some JS magic than only exists for logged in users? At ro.wp we have some custom entries in that section, but they should apply for all the users. I don't know about en.wp. I was unable to reproduce bug 31847, either logged in or anonymously, so I assume they're not the same bug.
Also happens at the Commons (IE8/Win7). Same cause and fix as bug 32241. *** This bug has been marked as a duplicate of bug 32241 ***
