+ fix #24466 + Adds support for exposing the `pageerror` events via `browserContext` API. + Helps with capturing the overall exceptions that are thrown outside of the the current page and also captures the exceptions happens on other windows/popups. + Keeps the API in sync with `context.on('request)', context.on('console'), etc..`
