+
+Previously, there was an issue where combining strikethrough (`s` element) and font size formatting could lead to incorrect rendering in some browsers, particularly Chrome. This occurred when the `s` (strikethrough) element was placed outside a font size span, causing the strikethrough line to render incorrectly.
+
+The fix ensures that the `s` element is now properly nested inside the font size element, improving visual consistency across browsers.
