Steps to reproduce

Items in a flexbox appear to be centered within the offsetHeight of their container instead of the clientHeight.

This happens regardless of the methodology used for vertical centering:

  1. “flex-direction: column” container with “justify-content: center”
  2. “flex-direction: row” container with “align-items: center”
    3: “flex-direction: column” container with auto-margin item
    4: “flex-direction: row” container with auto-margin item

See the attached test case. In all of the vertical centering examples the vertical position of the centered item is off by roughly half a scrollbar size.
