Code Issues

use page.on('popup') instead of page.opener() for popup detection

Browse Source 
page.opener() produced false positives during CDP reconnection because
existing pages re-enumerated via context.pages().forEach would sometimes
have a non-null opener. page.on('popup') only fires for actual
window.open() and target=_blank interactions, so it's safe to attach
on both new and existing pages without false positives.
