"Topics" navigation bar on the left resets the language
Steps to reproduce:
Visit https://support.torproject.org/, pick a language from the menu on the right. Or, just visit a language other than English directly, like https://support.torproject.org/de/. Then click on any of the topics on the left.
The support portal language resets to English.
The support portal language should respect the selected language and should not reset to English.
