Steps to replicate the issue (include links if applicable):

• Open jv.wikisource.org in mobile browser
• Set the input method to Javanese -> Transliteration
• Try to type something using regular qwerty keyboard layout on mobile, for example and ease of use, type something on the search box

I tried this both logged out and logged in.

What happens?:

• it didn't transliterate what I typed

What should have happened instead?:

• it should automatically transliterate what I typed, just like in PC browser.

Software version (skip for WMF-hosted wikis like Wikipedia):

Other information (browser name/version, screenshots, etc.):

Currently, the ULS page [1] and it's corresponding FAQ [2] says "The selection of user interface language will be only available for logged-in users ", but as a logged out user, I'm able to select the language. Either this statement is not true anymore (need to be updated), or it doesn't mean what I think it means.
