[Popper] transition issue

[ShDDaniel]

• This is a v1.x issue.
• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

Popper with transition should properly close without changing its size and/or position

Current Behavior

Before closing Popper changes its width and/or position.

Link:

1. https://codesandbox.io/s/y2j8qo7ppx (takes full screen width)
2. https://material-ui.com/utils/popper/ (Simple Popper example; it is visible by a scrollbar that page changes its height when button is clicked on; Popper moves to the bottom of the page)

Chrome 59.0
Ubuntu 16.04

Something is wrong with the position: aboslute style.

@ShDDaniel Thanks for the report.

Hello. This seems to be an issue on v5 as well (after migrating from v4 to v5). The element goes to the bottom of the page before disappearing and the scrollbar gets slightly larger just before the popper closes.
