The clientHeight documentation specifies: "Note: This property will round the value to an integer. If you need a fractional value, use element.getBoundingClientRect()."

However, element.getBoundingClientRect().height actually corresponds with element.offsetHeight, not element.clientHeight. element.clientHeight does not include the border or scrollbar height, while element.getBoundingClientRect() does include those in its dimensions.

The offsetHeight documentation has the same note, and it is correct for offsetHeight, just not for clientHeight.
