Cannot enter non-latin password characters in lock screen if layout set to english before lock

[kolen]

- Configure 2 keyboard layouts:
  - default: english
  - secondary: something else
- Set your password to something containing non-english characters
- Switch keyboard layout to English
- Lock screen
- Now you can't change keyboard layout on lock screen (hotkey does not work (#1244548) and there is no clickable layout indicator), so you can't enter password and unlock.

For some reason, clickable layout indicator appears on lock screen only if non-english layout (or non-default layout?) is active before locking screen.

Status changed to 'Confirmed' because the bug affects multiple users.

Same here. In fact, the layout indicator is there even in the default layout, however clicking it does not work anyway (you see it change but it does not affect the layout)
