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.
