| // https://www.w3.org/TR/2022/CRD-service-workers-20220712/#create-window-client |
| |
| // 1. Let windowClient be a new WindowClient object. |
| // 2. Set windowClient’s service worker client to client. |
| // Passed to Client constructor. |
| |
| // 3. Set windowClient’s frame type to frameType. |
| set_frame_type(window_data.frame_type); |
| |
| // 4. Set windowClient’s visibility state to visibilityState. |
| // 5. Set windowClient’s focus state to focusState. |
| // Determined in the property getter. |
| |
| // 6. Set windowClient’s ancestor origins array to a frozen array created from |
| // ancestorOriginsList. |
| // Not supported by Cobalt. |
| |
| // 7. Return windowClient. |
