Issue Summary

One can attach a document to a Confluence page and select between displaying the attachment as a thumbnail or as a link. By default, a thumbnail is displayed and one would have to click on it then select Show as link to display a link instead of a thumbnail.

When attempting to do that on Microsoft Edge, the operation enters an endless loop and attempts to display the file instead of converting the thumbnail to a link. Therefore, one is unable to convert attachments from thumbnails to links using Edge.

Steps to Reproduce

1. Create a page.
2. Attach any Office file to it.
3. Save the page.
4. At this point, the attachment should be displayed as a thumbnail.
   
5. Edit the page.
6. Click the thumbnail and click on Show as link.
   

Expected Results

Thumbnail is converted to link as can be seen below and one is able to save the page changes:

Actual Results

Edge actually opens the document contents and display them:

Once you close the preview you can save changes, but nothing really change as Edge is unable to convert the attachment to a link.

Workaround

Not exactly a workaround, but use any other browser instead of Edge.
