IsolateSandboxedIframes
for WebView2. - Fixed an issue where WebView creation fails when multiple instances are launched at the same time. (Issue #4731)

These Throttling Controls APIs allow you to:
- Customize script timers (
setTimeout
andsetInterval
) throttling under different page states (foreground, background, and background with intensive throttling). - Throttle script timers in select hosted iframes.
- Customize script timers (
