TextView doesn't scroll if necessary when a trigger is used

[Yuri Malheiros]

When I trigger is used and the cursor is placed outside user current text visualization the current TextView doesn't scroll.

For example, if your cursor is at last line and you hit Return a new line is created and the TextView scroll to show the cursor. But if you use a snippet that add text after the last line the TextView doesn't scroll. This is occur to auto indent, duplicate line, etc.
