[Windows][RTL] Arabic UI makes title bar navigation controls unclickable

What issue are you seeing?

When the ChatGPT desktop app is switched to the Arabic language while using the Codex view, the application switches to an RTL layout.

On Windows, the top title/navigation bar is mirrored in a way that places Codex navigation controls in the same area as the native Windows minimize, maximize, and close buttons.

The native Windows buttons remain fully clickable and take priority in that area. However, the Codex controls positioned underneath or behind them — including the sidebar button and the back/forward navigation buttons — become completely unclickable.

As a result, this is not only a visual overlap issue; it also completely blocks normal use of those navigation controls in the title bar.

This issue does not occur when the application language is set to English.

The title bar does not appear to reserve sufficient space for the native Windows caption buttons when the interface is displayed in RTL mode.

What steps can reproduce the bug?

1. Open the ChatGPT desktop app on Windows and switch to the Codex view.
2. Go to Settings.
3. Change the app language to Arabic.
4. Return to the Codex view and look at the title bar.
5. The Codex navigation controls overlap the native Windows minimize, maximize, and close buttons. The native Windows buttons remain clickable, while the Codex sidebar and back/forward navigation buttons become completely unclickable.

What is the expected behavior?

Arabic RTL support should work without affecting the native Windows title bar controls.

The Codex sidebar and back/forward navigation controls should remain properly positioned, fully visible, and clickable.

They should not overlap with the native Windows minimize, maximize, and close buttons.

The title bar should correctly reserve the Windows caption-button area in both LTR and RTL modes.

No response

Start by reproducing the issue through Settings: switch the Windows app to Arabic, return to the Codex view, and inspect the title bar. Trace the RTL title-bar layout around the sidebar and back/forward controls, then verify that those controls remain visible and clickable without overlapping the native minimize, maximize, and close buttons.
