Link in sys_file_reference.link is falsely displayed as broken link if in format <page uid>#<content element uid>

[sypets]

Describe the bug

sys_file_reference.link are now checked by default. If they contain a working link of the format e.g. 95476#684043, this is displayed as "page not found".

Something like this works though: t3://page?uid=95476#684043

Also, if there is a not working link to a CE in header_link, the CE id is incorrectly displayed as "Link to page", e.g.

header_link contains: t3://page?uid=108222#999999999

• page uid 108222 exists
• CE uid 999999999 does not exist
• problem: it is correctly found as broken, but in link list the "link target" shows the CE as "Link to page: [999999999]"

Important: the behaviour appears to be different between v12 and v13!

To Reproduce
Steps to reproduce the behavior:

1. Create a "Text & Media" with a file reference
2. For the file enter a link, use the format pageid#ce-id
3. check links
4. Link is displayed as broken

Expected behavior
The link should not be displayed in broken link list (if ok)
