Visible cue document has changed

In LibreOffice 26.2.5.2 620(Build:2) running on Fedora Workstation (Linux 7.1.10-200.fc44.x86_64 #1 SMP PREEMPT_DYNAMIC Sun Aug 23 16:15:11 UTC 2026 x86_64 GNU/Linux) I noticed that the star before the filename in the title bar indicating a document has been modified no longer appears. Is there a way to get it back? Thanks in advance for any hints.
