After update to 66.81.0.90: Settings/Ring shown incorrectly on T46S

[stefan]

On a T46S with firmware 66.81.0.90 (worked correctly with 66.81.0.70):

To reproduce:

• In the Web User Interface, go to “Settings”, then “Ring”.
• Set first “Internal Ringer File” setting to “Ring2.wav” (Corresponding to distinctive_ring_tones.alert_info.1.ringer=2)
• Press Confirm.
  

Observed behavior:
The page reloads, but shows the default “Ring1.wav” setting again. The phone setting itself works as expected and plays Ring2.wav as configured, so this is just a display issue in the Web UI.

Expected behavior:
The phone should show the current “Internal Ringer File” setting, not “Ring1.wav” unconditionally.
