Stabilizing Chromium's Wayland Support: Implementing and Testing Fallback Tab Drag...
summary
Chromium implements a fallback tab dragging mode for Wayland that uses a simple drag icon and only creates a new window on drop, as an alternative to the full-window behavior enabled by the xdg_toplevel_drag extension. A custom test protocol called UIControlsUnstable replaces Weston test to deliver one-to-one event semantics, plus emulated mouse resize/move to position adjacent windows; this fixes flakiness so all relevant end‑to‑end tests pass except those requiring key events during an active drag, which Wayland cannot deliver.
