Confluence_detailssummary does not correctly show images from details

[lucaa]

Describe the bug
When using the detailssummary bridge for pages that have images in the details macro, the images are not correctly displayed in the pagedetailssummary result.

Steps to reproduce

1. Create a page with a details macro
2. Add an image in one of the values of the details macro. The image displays correctly in the source table.
3. Create a page with the detailssummary macro, that displays the column with the image

Expected behavior
The image is displayed in the page with confluence_detailssummary macro

Actual behavior
The image is not found when displayed in the confluence_detailssummary macro, a broken image is displayed instead.
The actual result depends on how the browser displays broken (not found) images (here is an example from Firefox).

Environment (please complete the following information):
