macOS: Full-screen window state is not restored after relaunch

[sdtaheri]

Description

I usually use NetNewsWire on macOS in full-screen mode, where the app occupies its own Space in Mission Control.

When NetNewsWire is relaunched, it does not restore that full-screen state. This happens after restarting the Mac and also after manually quitting NetNewsWire with Cmd+Q and opening it again.

Instead of reopening full screen, NetNewsWire always opens as a small window positioned in the bottom-left corner of the screen.

This happens whether on my MacBook's screen or a connected 5K monitor.

Steps to Reproduce

1. Open NetNewsWire on macOS.
2. Put the main window into macOS full-screen mode.
3. Quit NetNewsWire with Cmd+Q, or restart the Mac and reopen NetNewsWire.
4. Observe the window state after launch.

Expected Result

NetNewsWire should reopen in the same full-screen Space, or at least restore the previous window size and position.

Actual Result

NetNewsWire opens as a small normal window in the bottom-left corner of the display.

Environment

• NetNewsWire version: 7.1.1 (Build 7108
• macOS version: Tahoe 26.5.2 (25F84)
• Mac model: MacBook Pro 14-inch, 2021
• System setting “Close windows when quitting an application”: Off
