Although Playwright selectors do not pierce closed shadow roots,
one can still obtain a reference to an element inside a closed shadow root:
- through `page.evaluate()`;
- through `handle.$()` where `handle` is inside the shadow root;
- through `frame.locator()` by choosing an iframe that belongs
to a closed shadow root.
In this case, `click()` action fails during the hit check test,
but it's possible to make it work by going bottom up from the target
rather than top down from the document.
Instead of requiring all frames in the subtree to receive a particular
event, we rely on the browser's definition of load and DOMContentLoaded.
This changes logic in a few edge cases:
- Some browsers do not emit load event upon window.stop() at all.
- DOMContentLoaded does not wait for subframes, so they might not be
ready when passing `{ waitUntil: 'domcontentloaded' }`.
`networkidle` preserves the old logic.
This patch changes `expect(locator).toHaveAttribute()` so that the
`value` argument can be omitted. When done so, the method will
assert attribute existance.

Fixes#15483
We lack `documentId` when doing a reload over browser protocols, so
`reload()` waits for the next navigation to finish. Sometimes, the page
might issue a same-document navigation while reload is in progress,
which confuses the reload command.
To fix the issue, just ignore same-document navigations for reload,
because it is always a new document.
This aligns all retargeting in a single place, so that we
can pass around "retarget strategy" to make sure we retarget
as expected in every single action.
