We skip waiting for "visible" state that enforces non-zero size.
Other invisible conditions like "display:none" fail during the
actual "scrolling" step and will retry.
These methods are useful for verification in tests, e.g.
```js
expect(await page.isEnabled(':text("Remove All")')).toBe(false);
await page.click(':text("Add Item")');
expect(await page.isVisible('.item:text("new item")')).toBe(true);
expect(await page.isEnabled(':text("Remove All")')).toBe(true);
```
