Revert of Percent height content should respect the fixed height of its containing cell

Revert of Percent height content should respect the fixed height of its containing cell (patchset #4 id:60001 of https://codereview.chromium.org/992483002/)

Reason for revert:
Broke Hangouts

Original issue's description:
> Percent height content should respect the fixed height of its containing cell
> 
> When an element in a cell has a percent height and the cell has a fixed height we
> currently let the element ignore the height on the cell and instead let its content
> determine the height of the cell (and the row).
> 
> Instead we should follow FF/Presto/Edge and the rendering agreed on the WG list
> and let the element calculate itself as a percentage of its parent, the cell's
> height.
