[BUG] BrowserContext should be aware of pages opened by external sources

BrowserContext.pages() does not know if a page is opened by a source other than Playwright. If an app other than Playwright opens a page, it doesn’t get added to context.pages(). This includes the recommended pattern from the docs:

If the action that triggers the new page is unknown, the following pattern can be used:

// Get all new pages (including popups) in the context
context.onPage(page -> {
  page.waitForLoadState();
  System.out.println(page.title());
});

The event is not emitted if a page is opened by an external source. It is emitted with context.newPage(), however

Thanks again for all the help. Playwright has been a real game changer for me. Makes UI test automation far easier, faster, more reliable, and more maintainable.

Closing this issue as you seem to have a solution for the problem. Meanwhile, we’ll keep collecting feedback on how the events are dispatched to listeners to see what API would work better.

Feel free to reopen if you need more assistance.
