Description Di 2022-11-21 10:40:49 PST 
For <meter> elements, we should use `block-size: 1em` instead of `height: 1em` and `inline-size: 5em` instead of `width: 5em`.
This change will not affect existing behavior for horizontal writing mode (the specced behavior) and help support vertical writing mode.

See spec PR: https://github.com/whatwg/html/pull/8536
