Annotation view: selection for new bounding box gets duplicated

[fredericobormann]

Expected behavior

When there is a selection for a new bouding box, there should not be a second one above it.

Current behavior

In some cases (s. Steps to Reproduce) the picture with the already drawn bouding box gets darker and darker and sometimes there is a second selection above the old one which can be moved.

Steps to Reproduce

1. Make an annotation and use "keep selection for next image"
2. Go to the next image with 'F'
3. Use the Image list on the left to go to a previous image.
4. Go back to the image you reached in step 2.
5. Use j, k, l, i to move the selection. Instead of moving the picture will get darker.
6. Some combination of using the mouse to move the selection and then trying to move the selection with j, k, l, i will result in two selections.
