            Bug ID: 247754
           Summary: Use block-size and inline-size for <progress> element
                    native appearance
           Product: WebKit
           Version: Safari 16
          Hardware: Unspecified
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Forms
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: dizhangg at chromium.org

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.

See spec PR: https://github.com/whatwg/html/pull/8471
