|
|
* Playwright would scroll it into view to click it, moving the scroll position — fatal to any test
|
|
* that then asserts on where the feed was. Being inside the viewport is not enough either: a card
|
|
* can sit under the page chrome above the scroller (the update banner, the toolbar band), and the
|
|
* covered click makes Playwright scroll and retry — the same move (webkit failed 3 in 24).
|
|
* So the link must be the element hit at its own centre. Returns false if none found.
|
|
* Looked for again until one is, not once: a fresh load is still settling when the first card shows
|
|
* (the links move down ~55px), and webkit can answer the hit test at a link's new centre with the
|
|
* card under it — every link missed in 1 of 30 runs.
