 Updated feature entry:
Unframed display mode for Isolated Web Apps
Updates made by edm...@google.com:
  • name:
    Old: Unframed mode (f.k.a. borderless)
    New: Unframed display mode for Isolated Web Apps

  • summary:
    Old: Unframed mode extends the Isolated Web App (IWA) client area to encompass the entire window, including the regions normally reserved for the title bar and system window controls. This provides developers with complete control over the application's visual layout, enabling bespoke, immersive experiences and custom window branding. In this mode, the application is responsible for rendering all visual elements and handling user input across the entire window surface.
    New: Extends the Isolated Web App (IWA) client area on ChromeOS to encompass the entire window by removing the standard title bar and window controls. This mode requires the Window Management permission and dynamically restores the window frame if the browser needs to display security warnings or prompts.

This mode requires the Window Management permission and dynamically restores the window frame if the browser needs to display security warnings or prompts. Administrators can manage with the existing policies for the window-management permission: * DefaultWindowManagementSetting: Configures the default behavior for the Window Management permission. * WindowManagementAllowedForUrls: Explicitly grants the permission to specified IWA origins, allowing them to enter unframed mode without any user interaction. * WindowManagementBlockedForUrls: Blocks the permission for specified origins, forcing Chrome to fallback from unframed to other display modes.
