Table Summary Property Size Styling #23139

💡 Background and solution

While using the <Table> element with a summary property I realized that the size property styling was not applied to the tfoot element. This fix is to include the tfoot > tr > th and tfoot > tr > td in the styles for tables that use the size property.
