Wrong location for left/right positions when some parent has position:absolute

[gdenisov]

When a parent has absolute position "left" and "right" positions seem to be broken and place the content at the right horizontal position but wrong vertical position (the content is placed outside of the view frame at the top of it).

Minimal demo here: https://codesandbox.io/s/lucid-ride-b8dw3w?file=/src/styles.css

Below images assume positions={["left"]} and align="center"

Expectation:

Content div appears to the left of the trigger element and is center aligned in relationship to it.

What happens instead:

Here we see a peek of the content div at the top of the screen due to browser's default 8px margin on the body element.

@alexkatz Any chance of looking in to this? Trying to display in the context of a modal which is centred absolutely.
