BUG: Inside a cell, "height:x%" is ignored. It looks like 'auto' is used instead.
Absolute units work correctly (eg. 50px).
"width:x%" works correctly.
BUG: the height of the textarea is not 80%
OK: the height of the textarea is 80 pixels
BUG: the height of the P is not 80%
OK: the height of the P is 80 pixels
