In Tamil Wiktionary, the anchor link on the "tab caption" doesn't exist for the main page. If one goes to http://ta.wiktionary.org/wiki/%E0%AE%AA%E0%AF%87%E0%AE%9A%E0%AF%8D%E0%AE%9A%E0%AF%81:%E0%AE%AE%E0%AF%81%E0%AE%A4%E0%AE%B1%E0%AF%8D_%E0%AE%AA%E0%AE%95%E0%AF%8D%E0%AE%95%E0%AE%AE%E0%AF%8D (http://ta.wiktionary.org/s/x0f), it can be seen that there's no link to click to come back to the main page (except for the universal link behind the logo).
the Same bug on Malayalam Wiktionary http://ml.wiktionary.org/wiki/%E0%B4%AA%E0%B5%8D%E0%B4%B0%E0%B4%A7%E0%B4%BE%E0%B4%A8_%E0%B4%A4%E0%B4%BE%E0%B5%BE
The tab is linked for me
