Description Di 2022-11-10 11:26:20 PST

For <progress> elements, we should use `block-size: 1em` instead of `height: 1em` and `inline-size: 10em` instead of `width: 10em`.
This change will not affect existing behavior for horizontal writing mode (the specced behavior) and help support vertical writing mode.
