On macOS, I set System Settings -> Desktop & Dock -> "Double-click a window's title bar" to "Fill".

In Firefox, double-clicking the window title bar does nothing. If I change the macOS setting to "Zoom", double-click works correctly in Firefox doing Zoom effect.

I confirmed that other applications respond correctly to the "Fill" setting.

Environment: - macOS version: 26.3 - Firefox version: 147.0.4 (aarch64)
