Positionable Elements Can Extend Off Screen

[mcortez1497]

Describe the Bug

Popovers/Menus (I think any hoverable Helix elements) that extend off of the screen do not extend the screen or reposition to be within view.

Steps to Reproduce

Steps to reproduce the behavior:

1. Have a page where a hoverable element would be opened off the bottom of the screen
2. Toggle the element as open
3. Portions of the element will be unviewable, no scroll or other over available

Expected behavior

Previous positioning behavior would ensure that the element be visible on the screen, i.e. if a popover positioned downwards extended off the bottom of the page, the toolkit repositioned it to open upwards. With the new positioning logic, I'm not sure what our expectation should be.

Thanks @mcortez1497 for submitting this issue! We removed smart positioning which would have accounted for the previous behavior.

Smart repositioning logic will be reimplemented in the near future, but it likely won't be with the 0.15.0 release.

EDIT: Results from a successful spike have made it possible to include this functionality in the upcoming v0.15.0 release.
