Revisit Tooltips (spike)

Goal is to reconsider the arcitecture of the tooltip for 1.0. Wrapping an element and adding a ref, then adding a relatively positioned tooltip to that.

Another option is to move to the coordinates of an element. May be more robust with less issues.

Do we want to switch out the underlying library that we use for the tooltip?

What are the pros/cons of the 2 approaches. Is option 2 better? How much would it take to implement? Also we want our solution to fix the currently open bugs (#393, #380, #369)

Acceptance criteria:
- should have a branch with a different approach
- should fix the 3 bugs listed
- should document api changes
