Batch "Cleanup entries" function does not work if order by file name

[avm19]

The following operation:

Quality -> Cleanup entries -> Make paths of linked files relative (if possible)

does not work properly if applied to a group of selected entries when the entries are sorted by "File".

Steps to reproduce:

• [provided some files in the database have absolute path in the "File" field and can be converted to relative paths, and the base directory path is specified for the database to make it possible]
• select those files (shift+Click)
• Quality -> Cleanup entries -> check Make paths of linked files relative (if possible), uncheck everything else
• Ok

Expected behaviour:
The operation is applied to all files (abs. paths change to relative ones)

Observed behaviour:
The operation is completed in respect of no more than one entry.

User fix:
If the database is sorted by a different field / column, then everything works as expected.

It is reasonable to suspect that the bug is due to the group of entries being referred by their current position in the database list. After the operation is completed for one file, the order of the entries in the list is changed.

Apologies for having it tested only for 2 weeks old master build. If someone fixed it within last 2 weeks, it should be easy to remember. (Also the bug doesn't seem to be very important)

This issue has been inactive for half a year. Since JabRef is constantly evolving this issue may not be relevant any longer and it will be closed in two weeks if no further activity occurs.

As part of an effort to ensure that the JabRef team is focusing on important and valid issues, we would like to ask if you could update the issue if it still persists. This could be in the following form:

• If there has been a longer discussion, add a short summary of the most important points as a new comment (if not yet existing).
• Provide further steps or information on how to reproduce this issue.
• Upvote the initial post if you like to see it implemented soon. Votes are not the only metric that we use to determine the requests that are implemented, however, they do factor into our decision-making process.
• If all information is provided and still up-to-date, then just add a short comment that the issue is still relevant.

Thank you for your contribution!
