getAnchoredPosition returns position without perfectly aligned edges

[khiga8]

Context

We use getAnchoredPosition for primer-tooltip positioning (which is soon to be upstreamed to PVC).

In some scenarios, we observed the tooltip is not perfectly aligned at edge, particularly when there's no space for perfect edge alignment. Here is an example where align is end.

I was also able to recreate this issue in storybook:

Expected behavior

Since there’s no space to perfectly align end, I would have expected anchorAlignment to be adjusted to start instead. Is that not expected behavior?

For now, we're thinking of housing additional positioning logic in tooltip to address immediate issues, but this should probably be responsibility of getAnchoredPosition.

Thanks Kate! Added this to the primer-react board to prioritise it!

Yay @siddharthkp! Will you let me know once this has been worked on so I can remove the extra logic from tooltip code? Thank you ☺️
