Comment 2 for bug 1271494

So, fixing this in ubuntu-keyboard is a bit more complicated and problematic - and would have a lot implications. The very design of pre-edit (as with word propositions) is not to commit the string to the entry field until it's finished. We would have to change this rule and actually commit all the time and then try to 'edit' the text field when in pre-edit, which seems strange.

I prepared a fix for messaging-app instead that flushes the pre-edit before sending the SMS. Seems a better, less invasive approach.
