When creating a new annotation, frames beyond the adjacent annotations should not be shown

Steps to reproduce the bug:

• Create an annotation
• Start creating an annotation to the right of the first one
• Type the Left continuously

Result: The left border of the annotation being created will move to the left until it reaches the right border of the first annotation. The left border of the annotation being created will not go beyond that point. However, the position n the movie continue to be changed.

The problem also happens when creating a new annotation at the left of the first one.
