netbeans Non-ascii file names on editor tabs lack filename extension after dot

Apache NetBeans version

Apache NetBeans 19

What happened

I have a project with cyrillic filenames with standard filename extensions like 'имя1.txt', 'имя2.sql'. Never have had any issue about that with NetBeans versions prior to 19. Now NetBeans 19 does not display filename extension after the dot on the file tab in the editor. That is, filenames are displayed on the tab like 'имя1.', 'имя2.'. While Project Explorer window does display full file names correctly. screenshot1

How to reproduce

Apache NetBeans 18

Operating System

Windows 10

JDK

Apache NetBeans packaging

Apache NetBeans provided installer

Anything else

Stable problem in NetBeans 19

I can't reproduce this on NB 19 / Linux / JDK 20.0.2, wondering if it is a windows specific issue again

Not reproduced with latest windows build with java 18.0.2
