At least in Mongolia, Cyrillic is dominant and usage of the traditional script is marginal, though there are efforts to bring it back.
Most users of traditional Mongolian script are in China, where websites are in Chinese by default and Mongolian form elements are rare. They do exist though, and it would be nice if the search bar of this bookstore https://mn.dayangds.com/ could be vertical like everything else.
Looks like mn.dayangds.com does UA sniffing so you only get the vertical search bar if the user-agent contains the string "Firefox/" followed by at least one digit. Ugh.
