Bug 157699

Description:
I'm trying to embed PDF documents into a DOCX file via the following sequence of commands:

Insert > OLE Object > Create from file > Display as icon

This initially works, and results in a generic file icon that links to the embedded PDF file. I would have preferred an icon that looks like the Adobe PDF logo, but I can live with the generic file icon.

However, if I close the DOCX file and then reopen it, the icon link no longer works. When I click on the icon, the Image Properties dialogue box is now displayed.

This incorrect behaviour happens every time.

(I'm running LibreOffice Community version 7.5.7.1 on Debian 13.)

Steps to Reproduce:
1. Open LibreOffice TextMaker
2. Go to File > Save as and save file in DOCX format
3. Go to Insert > OLE Object > OLE Object
4. Select the "Create from file" radio button
5. Check the "Display as icon" checkbox
6. Click on the "Search" button
7. Select a PDF file that's stored locally
8. A generic file icon will be displayed 
9. Click on the icon to ensure it links to the embedded PDF file.
10. Save document
11. Close document
12. Reopen document
13. Click again on the icon to ensure it links to the embedded embedded PDF


Actual Results:
14. Clicking on the linked icon results in the Image Properties dialogue box


Expected Results:
14. Clicking on the linked icon should result in the embedded PDF being displayed



Reproducible: Always


User Profile Reset: Yes

Additional Info:
In step 8, instead of a generic file icon, I would have preferred the Adobe PDF icon, or something similar. As it stands, it is not clear that the icon links to an embedded PDF file.
