## Summary macOS 27 Beta delays clicks in titlebar regions while AppKit determines whether a gesture should become a drag, single click, or double click. Zed's main workspace windows render a custom titlebar that already handles window movement via `Window::start_window_move`, so they do not need AppKit's native movable-titlebar behavior. This sets `is_movable` to `false` for the main `MultiWorkspace` windows and documents the `WindowOptions::is_movable` caveat for GPUI users with custom titlebars. ## Background The previous fix for this, #58947, used AppKit's private `_opaqueRectForWindowMoveWhenInTitlebar` SPI to mark GPUI's full-size content view as app-owned titlebar content. That fixed delayed titlebar clicks, but was later reverted in #59214 because it also affected windows that rely on AppKit's native titlebar dragging, like the settings window. This PR takes a narrower approach by only changing Zed's main custom-titlebar windows. Those windows already implement dragging explicitly via `Window::start_window_move`, so disabling AppKit's native movable-titlebar behavior fixes the macOS 27 Beta click delay without affecting other window types. Release Notes: - Fixed delayed clicks in the custom titlebar on macOS 27 Beta.
