When multiple images are embedded, the menu of the first selected Image-Embed will be kept when selecting another image afterwards.
This results in the wrong alias-selection being displayed in edit.

Steps to reproduce:

1. Create new Content containing Richtext-Type
2. Add 2 Images via Image-Embed
3. Change the second image to use a different Image-Alias (e.g. small)
4. Publish the content
5. The correct and selected aliases be used in location-view
6. Open the edit view for the content
7. Select the first or second image (correct alias displayed)
8. Select the other image depending on the first selected
9. Image alias selected on the first embed will be displayed (selection does not update correctly and the stored data remains unchanged)
