Issue Summary

When the Attachments macro is added to an overview page, the drag and drop functionality stops working after a file is added. To make it work again, the page must be edited and saved. However, it will only work once, and after that, it throws an HTTP error. This issue occurs only when the Attachments macro is placed on an overview page.

This is reproducible on Data Center: (yes) / (no)

Steps to Reproduce

1. Add the Attachments macro to an overview page.
2. Drag and drop a file to the page.
3. The file will be attached correctly
4. Try to upload another file
5. Observe that the drag and drop functionality stops working.
6. After the first use, an HTTP error will occur when trying to drag and drop another file.

Expected Results

The drag and drop functionality should continue to work consistently without requiring the page to be edited and saved again.

Actual Results

The drag and drop functionality stops working after a file is added, and it only works again after editing and saving the page. However, this will only work once before an HTTP error is thrown.

The below exception is thrown in the xxxxxxx.log file:
