WebDriver/RemoteProtocol/WebDriver BiDi/Milestone 17

WebDriver BiDi Milestone 17 - In Planning

Goal: In this milestone, we are expanding WebDriver BiDi’s emulation features to make it easier to simulate locales, timezones, mobile devices etc. We are also adding support for retrieving network response bodies, which has been strongly requested by clients. Those features benefit existing WebDriver BiDi clients, and are also key requirements for Playwright adoption. Internally we keep supporting Desktop Test Engineering by improving our support for chrome privileged script evaluation and widget-level events.
