If content assist is active, and the user types in a character that makes CA go away, then deletes that character, content assist should reappear. Currently content assist goes away and stays away. If content assist is reactivated in this state, the word will auto-complete because CA activation and word-complete have the same shortcut. See sequential screenshots. This is a usability issue.
Steps to Reproduce:
1. Enter Ti.UI.create
2. Add one character that does not exist in the proposal list, such as: Ti.UI.create7
3. Delete the last new character, such as: Ti.UI.create
Content Assist does not reappear.
Content Assist should reappear.
