no issue
- followed the migration guide to switch to from lifecycle hooks to single `modify()` method
- https://togithub.com/ember-modifier/ember-modifier/blob/master/MIGRATIONS.md
- forced resolution of `ember-in-viewport@4.0.2` to avoid older version of `ember-modifier` being pulled in through `ember-infinity`

When the gif selector is activated we want to scroll as much of the picker into view as possible.
- updated `scroll-into-view` modifier so it can work on bounding rects as well as offsets for those situations where a scroll parent is not the offset parent
- only implemented "off bottom" behavior for now as that's all we need for this use-case
- if the scroll adjustment would mean the top is cut off we readjust so that the top of the element is always visible

- added `scroll-into-view` modifier that will scroll an element into view putting it at the top or bottom of the viewport depending on which direction scroll is required
- used the `scroll-into-view` modifier to scroll the highlighted gif into view
