DOM renderer may clip overline

[Tyriar]

It works in this browser (Edge/macOS) but gets clipped because of overflow:hidden.

Eww still so many issues with the DOM renderer, seems it fall a bit behind over the years 😅

Overline is approximately equal to the underline on the previous line and has been processed by overflow.Should we use a special method to handle it?...

@tisilent I think that would be fixed automatically, once we resolved #4632.

@jerch I was looking into general renderer playwright tests yesterday and the progress is promising 🙂
