WebDriver/RemoteProtocol/WebDriver BiDi/Milestone 16

WebDriver BiDi Milestone 16 - In Development

Goal: One key focus in this milestone is enhancing WebDriver’s ability to simulate user interactions accurately using widget-level events. These improvements are critical to unblocking the APZ team’s work on wheel scroll events and will enable them to complete writing tests in the scrollend focus area for Interop 2025. We’re also continuing our collaboration with the Playwright and Puppeteer teams to support their needs. This includes implementing new features such as the emulation of geolocation and language settings.
