Describe the bug
An edge case for having a not native dropdown at the end of the page. There are actually 4 items that could be selected but he save bar overlaps the last item.

Expected behavior
Be able to select all items 😉

Kirby Version
3.0.3

Desktop

• Windows 10
• Firefox 66

Additional context
It's not that big of deal. More like an annoyance. The problem also only occurs if you try to add more than one item in one go. Chrome kinda works as the last item is at least visible.
