Description DarkTrick 2020-12-27 10:33:23 UTC
Summary
=======
If you put an "anchor element" (something, that you can cross reference) inside a section (mark->insert section) and then revert the action of inserting a section, all references to that anchor will become invalid.


Reproduce
==========

1. Create a numbered element (e.g. a numbered list)
2. Create a cross reference to that numbered element
3. Select everything and execute `Insert`-> `Section...` -> `Ok`
4. (Everything gets put in a section)
5. Press Ctrl+Z to revert the inserted section
6. Mark everything and press F9 to refresh all references
7. ACTUAL: The references became invalid
7. EXPECTED: References don't change / don't become invalid

The actual result is irreversible. All references are marked as "Error. Reference source not found". It's impossible to easily restore references except, if an older version of the document exists.
