CSS inset border radius with solid border

Question

I know that I could create inset/inverted borders playing with radial-gradient, like here: Inset border-radius with CSS3, but what I want to know is if I can draw a solid border of 1px around the resulting shape, like in this image:

I don't only want the bottom-left radius inverted by also a border, and the background color inside the remaining space must be transparent. Is it possible with CSS3 and HTML (I am not interested in canvas or SVG for now)?

the demo: Jsfiddle here

Code

figure {
  position: relative;
  width: 200px;
  height: 120px;
  margin: 100px auto;
  overflow: hidden;
  border: 1px solid black;
  border-right: none;
  border-bottom: none;
  border-bottom-left-radius: 5px;
  border-top-left-radius: 5px;
}

figure:before,
figure:after {
  content: '';
  position: absolute;
}

figure:before {
  right: -50%;
  top: 0;
  background: transparent;
  width: 172px;
  height: 200px;
  border: 1px solid black;
  border-radius: 100%;
  box-shadow: 0 0 0 100em red;
}

figure:after {
  left: -1px;
  bottom: 0px;
  height: 16px;
  width: 128px;
  border-top-left-radius: 0;
  border-bottom-left-radius: 5px;
  border-left: 1px solid black;
  border-bottom: 1px solid black;
}
