The default style of the <rp> element is changed to "display:none" instead of "display:inline" even if it is not inside the <ruby>element as defined in HTML specification. This behavior is implemented in the UA style sheet, but the web author can override it. Behavior in other browsers: - Edge: display:inline (outside <ruby>), display:none (inside <ruby>) - Firefox: display:none - Safari: display:inline, display:none (inside <ruby>)

So far, <rp> is display:none if it is in <ruby> as in UA style sheet: `ruby > rp { display:none }` After launching this, <rp> is display:none even if outside of <ruby>.
