fd63510ca9* feat: add serial api support resolves #22478 * Put serial port support behind a flag and mark as experimental * Update docs/api/session.md Co-authored-by: Jeremy Rose <jeremya@chromium.org> * Use enable-blink-features=Serial instead of enable-experimental-web-platform-features * Set enableBlinkFeatures on webPreferences instead of commandline Co-authored-by: Jeremy Rose <jeremya@chromium.org>
