Can you please verify that easy unlock icon doesn't interfere with this
indicator. It is shown when Caps Lock is on.

fyi, Alt+Search would show the caps lock indicator.

Right now, it would show on the left side of the lock icon. The padding could
use some polishments but both icons are visible and not overlapping.

As xiyuan said, the caps lock icon is shown to the left of the lock icon.
