Notes. Safari has no headless, BiDi, or CDP support — only basic navigation, interaction, screenshot, storage, and iframe work. Edge IE mode is Windows Enterprise only; the IE engine lacks Shadow DOM, emulation, BiDi interception, and recording — capabilities marked ◐ run in a degraded form (Actions chain steps, partial CDP for console/network monitoring). Capabilities marked ○ are scheduled but not yet shipped.
