Eprint field shows an additional action icon/control on the General tab even when no eprint/eprinttype is set

[SuYanqi]

JabRef version

Other (please describe below)

Operating system

GNU / Linux

Details on version and operating system

ubuntu:22.04

Checked with the latest development build (copy version output from About dialog)

• I made a backup of my libraries before testing the latest development version.
• I have tested the latest development version and the problem persists

Steps to reproduce the behaviour

1. Open JabRef
2. Create a new empty library
3. Create a new Article entry and open the entry editor
4. Go to the General tab
5. Observe the Eprint field row (right side of the field)

Expected Behavior

• No arXiv/eprint fetch control is shown unless an applicable identifier is present and the eprinttype indicates arXiv (or the control is clearly disabled/inactive when not applicable).

Actual Behavior

• An extra icon/control (e.g., magnifier/fetch action in box 27) is visible next to the Eprint field compared to before, even though no eprint/eprinttype has been entered yet.

Notes

Reproducible after merging #14458 , namely Commit: 029afb7

Appendix

Also applies to other magnifier/fetch action icons, which should be clearly disabled/inactive when the input is empty.
