On macOS, with an editable element focused and an input method active, WebKit can deliver a tap as pointerup then pointerdown, so drag trackers saw every later pointermove as a held button: one tap plus a pointer move started a phantom drag (file drag label, tab detach, tool window move) and the next tap dropped it. A drag now starts only from a move with the primary button down, a move without it cancels the press, and late button-less moves after a drag started are ignored so the drop is kept. Resizers, dialog drag/resize, pan and the review gutter end instead; the Project view also listens for pointercancel.

Dragging a tab showed no floating copy: the ghost cloned the tab's classes, and .tab { position: relative } loaded after .ghost { position: fixed }. The ghost is now positioned inline, and a tab dragged within its strip stays as an empty slot the other tabs move around; the insertion line for tabs from another strip is drawn inside the edge tabs so the scroller doesn't clip it. A terminal group is now a drop target like an editor pane: the middle joins the group, an edge splits off a new group (dropZoneAt moves to ui and is shared).

Dragging an editor tab past the window edge, or choosing Open in New Window from its menu, now opens the file in its own window and closes the tab here. A text file is saved first and a custom document runs its Save / Do not Save / Cancel guard once; if saving or opening fails, the tab stays. The new window is forced even when the project is already open elsewhere, and a file outside the project opens as LightEdit.
Dragging out tool windows is not covered. Refs #454
