I recently upgraded to MW 1.35 and timeless skin shows the language change dropdrown (on mobile view) even though my wiki has only 1 language. Here's a link to my wiki. Clicking on the toggle just opens a blank overlay with no options (since no other languages exist).
To summarise:
- On MW 1.35, the languages switch option appears in mobile mode (bug)
- On MW 1.35, the languages switch option does not appear in desktop mode (correct)
- On MW 1.34, the languages switch option does not appear in desktop and mobile mode (correct)
