Actions before raising this issue

• I searched the existing issues and did not find anything similar.
• I read/searched the docs

Steps to Reproduce

1. Create a task with 1 label of type "points"
2. Create a gt job
3. Try to annotate a normal job in Single Shape mode (uncheck the "Predefined number of points" checkbox)
4. Go to the last frame
5. Put a point
6. Click Submit

The last frame annotation will not be saved.

Expected Behavior

No response

Possible Solution

In single shape mode, when multiple points should be put, when the last frame frame is annotated, it would be nice to finish and save the current annotation, even without clicking N or Done, if the Submit button is clicked.
