Steps to reproduce:
1. Create new Unity project
2. In project press on “Layout” button at the top right corner
3. From the menu select “Reset All Layouts”

Actual results: The top title bar text with Editor version and project name disappears after layout reset

Expected results: The top title bar text with Editor version and project name should no disappear after layout reset

Reproducible with versions: 6000.3.0a3, 6000.3.0a5

Not reproducible with versions: 6000.3.0a1, 6000.3.0a2

Tested on (OS): macOS Silicon, Sequoia 15.6 (M1)

Notes:

•  closing and reopening project fixes the issue

UPDATE: This issue also occurs on Windows and Linux.

Since NativeWindowManager was integrated separately on each platform, I suspect each integration PR introduced the bug for their respective, but since the Reporter didn't check the other platforms, the Bisection only blamed the macOS PR.
