Closes#13131.
Per the visibility spec on https://playwright.dev/docs/next/actionability#visible:
> Element is considered visible when it has non-empty bounding box and does not have visibility:hidden computed style. Note that elements of zero size or with display:none are not considered visible.
✅ non-empty bounding box
✅ does not have visibility:hidden
Given the above conditions are satisfied, the locator is considered visible.
https://github.com/microsoft/playwright/issues/8740 proposes something like `isInViewport()` that would be better suited for checking if an element is offscreen.
