Issue Summary

When a user uploads multiple images to a card at once, the image position in the attachment section can't be changed, and the file appears to occupy multiple positions when dragging and dropping the images to a new position.

Steps to Reproduce

1. Have minimum of 2 local images ready to upload
2. Open a card
3. Select Add attachment from the Add menu on the card back
4. Select Choose file and select the two local images from step 1
5. Wait for files to upload, then attempt to reorder the attached images by dragging one to a new position in the attachment section

Expected Results

The UI clearly shows where the image is being placed, and stays in the new desired position.

Actual Results

The UI appears to shows the file in multiple locations while being dragged, and does not stay in its new desired position when dropped there

Workaround

Any one of the following:

• Attach images one at a time
• Attach the images by dragging them to the card back instead of through the attachment menu

Once the attachment section is in this state, there is no known workaround to fix it
