On my 2023 Macbook Air, when I have a second monitor plugged in via USB-C, any attempt to drag an open browser tab from an existing Orion window to the desktop to create a new window results in a hard lock of that Orion instance which must then be force-quit. The crash occurs whether attempting to drag the tab to the external monitor, or from the external monitor to the laptop screen, or even when dragging the tab to the same screen that the current window is open on.
If the external screen is detached, then it becomes possible again to drag a tab to the desktop on the laptop screen and a new window is created as expected.
Even with the external screen attached, it is possible to drag tabs successfully between already opened windows, whether they are on the same screen or another screen. The crash occurs only when attempting to move a tab to a new window. Also, using menu commands (right-clicking on the tab and selecting New Window) works without crashing, although obviously only to the current monitor.
When dragged to the desktop anywhere on any available screen, the tab should open in a new window on the screen on which it was dropped.
