This test checks that text controls with percentage heights within table cells have the correct height.Text controls are in a different test than other replaced elements because their metrics are platform-specific.The reason a 75% control is the same height as a 100% control is because a replaced element that depends on theheight of its parent cell is treated as auto. So by itself it will set the height of the row. See https://drafts.csswg.org/css-tables-3/#row-layout On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". PASS successfullyParsed is true TEST COMPLETE PASS getWidth('input-password-75') is getWidth('input-password-100') PASS getFullHeight('input-password-75') != '0px' is true PASS getFullHeight('input-password-75') is getFullHeight('input-password-100') PASS getWidth('input-text-75') is getWidth('input-text-100') PASS getFullHeight('input-text-75') != '0px' is true PASS getFullHeight('input-text-75') is getFullHeight('input-text-100') PASS getWidth('textarea-75') is getWidth('textarea-100') PASS getFullHeight('textarea-75') != '0px' is true PASS getFullHeight('textarea-75') is getFullHeight('textarea-100') PASS successfullyParsed is true TEST COMPLETE
