Created attachment 477805 [details] rendering of the example described in the comment When an anchor tag has a text decoration that differs from its parent in line and in style, the parent's line that crosses the anchor tag gets the decoration style as is set by the anchor tag. E.g. something like the following: <style> span { text-decoration: line-through solid; -webkit-text-decoration: line-through solid; } a { text-decoration: underline dotted; -webkit-text-decoration: underline dotted; } </style> <span>some text and <a>a link</a></span> FWIW, with Firefox and Chrome, the text-decoration-line is not affected by the line style of the anchor tag.
