>The checkin 84a3793b194efe92e2eb80cd0f625f3324bf4cae have introduced autocompletion issues at various places. To reproduce, I have tried these steps. I have also tried it on one previous commit (3c86424a182892db1e0216b9aa7e8389ae6f13de). This commit is ok; which implies that the issues has occurred in commit 84a3793b194efe92e2eb80cd0f625f3324bf4cae only. 

You probably mean 0b21ecdb5e, not 84a3793b19. I can confirm that reverting 0b21ecdb5e fixes the problem.
