Tadashi G. Takaoka 6769c67987 Fix automatic temporary upper case mode behaviour
This change is a followup of I948ef26f

Automatic Temporary Upper Case mode acts like Normal mode until shift
key is pressed. However, after shift key is pressed, it acts like
Manual Temporary Upper Case mode.

Bug: 3193390
