Is onOrientationLockChanged ever executed? [released]
Line 161 in /usr/share/jolla-settings/pages/display/display.qml
onOrientationLockChanged: orientationLockCombo.currentIndex = orientationLockIndex(orientationLock)
shows that when orientationLock is changed, the combo box displaying the lock state should update itself to show the current state.
However, we can keep the settings/display page open and launch another instance of settings app (from the terminal) and set the orientationLock, the state in the combo box of the original instance does not update automatically.
Edit: The signal 'orientationLockChanged' was not emitted when it should be, which caused this issue. It has been fixed in update 10.
