### `getOptimalPosition()` with the `limiter` resticted by overflowed parents [#146](https://github.com/ckeditor/ckeditor5-utils/issues/148) Vertically scroll the container up and down. **Expected**: 1. The red square should **always** remain visible regardless of the position of the scroll. 2. In the initial position, the shapes should represent a small letter "i", with the red dot above. 3. In the opposite scroll position, the shapes should represent an exclamation mark "!" with the red dot underneath.
