Office documents not properly previewed on some pages

STEPS TO REPRODUCE

Prerequisites: The Office Server must be configured and connected.

1. Create a L1 nested page "a1"
2. Create a new child page "a2"
3. Create a new child page "a3" (make it a Terminal page)
4. Create a L1 Terminal page "b1"
5. Go to Attachments of the created pages and attach an Office document containing images (must be the same), e.g. "sample - Copy.doc"
6. Click on the "Eye" Icon for previewing the attached document on every page

EXPECTED RESULTS

The attached document (text and images) is properly displayed on any page.

ACTUAL RESULTS

The document is properly displayed only on L1 Terminal page "b1". On the WebHome pages "a1", a2" and Terminal child page "a3", the images are not displayed (instead, a local link to the images appears).

There is also an issue with the "Eye" Icon. For more information, see XWIKI-14513
