Stretch SVG to fit 100% height and width of its parent

Question

(Solved - see solution via codepen link) I am trying to use an SVG image as a background that will always stretch to 100% of its parent div. Already tried:

• Use as CSS background-image and set background-size: 100% 100%.
• Put absolute to parent div and set height:100%.
• preserveAspectRatio="xMaxYMax".
• even if I manually change the viewBox it dosen't work.
• tried all the related questions I found here - Stretch SVG background image?, Automatically scale an SVG to its parent, Fit/Stretch SVG to div background without reescaling

To get better understanding of what I want, please visit this link: http://185.127.16.178/~amen/%D7%90%D7%95%D7%91%D7%97%D7%A0%D7%AA-%D7%9C%D7%90%D7%97%D7%A8%D7%95%D7%A0%D7%94/
In that green bubble, the text's length can vary, so I need the SVG to stretch when more text is added and the div is growing.

I also created a small pen -

.svg-container {
  height: 400px;
  width: 200px;
  border: 1px solid red;
  position: relative;
}

#small_bubble {
  top: 0;
  right: 0;
  width: 100%;
  height: 100%;
}

.cls-1 {
  fill: transparent;
  stroke: green;
  stroke-miterlimit: 3;
  stroke-width: 3px;
}

.e-poa {
  position: absolute;
}

e-por {
  position: relative;
}

<div class="svg-container">
  <svg id="small_bubble" class="e-poa" xmlns="http://www.w3.org/2000/svg" viewBox="0 0 311.92 272.85" preserveAspectRatio="xMaxYMax">
      <path class="cls-1" preserveAspectRatio="xMaxYMax" d="M301.52,1.57,8.37,19.53A7.87,7.87,0,0,0,1.5,27.34V214.76a7.89,7.89,0,0,0,7.12,7.85l46.67,4.53-7.14,42.78,63-37.35,190.58,18.51a7.88,7.88,0,0,0,8.65-7.85V9.38A7.88,7.88,0,0,0,301.52,1.57Z"/>
     </svg>
</div>

If you are open to another alternative you can create the shape with pure CSS. It won't be neat as the SVG one but it will be responsive:

* {
 box-sizing:border-box;
}

.box {
 margin:40px;
 padding:0 10px;
 max-width:200px;
 display:inline-block;
 vertical-align:top;
 border-right:2px solid green;
 border-left:2px solid green;
 position:relative;
}
.box:before {
  content:"";
  position:absolute;
  left:-2px;
  right:-2px;
  bottom:calc(100% - 40px);
  height:50px;
  border:2px solid green;
  border-bottom:0;
  border-radius:5px 5px 0 0;
  transform:skewY(-5deg);
  transform-origin:left bottom;
}
.box .b {
  position:absolute;
  left:-2px;
  right:-2px;
  top:calc(100% - 40px);
  height:50px;
  border:2px solid green;
  border-top:0;
  border-radius:0 0 5px 5px;
  transform:skewY(5deg);
  transform-origin:left top;
}
.box .b:before {
  content:"";
  position:absolute;
  width:30px;
  height:30px;
  top:calc(100% - 15px);
  left:40px;
  border-left:2px solid green;
  border-bottom:2px solid green;
  transform:skewY(-45deg);
}
.box .b:after {
  content:"";
  position:absolute;
  width:27px;
  height:4px;
  top:calc(100% - 1px);
  background:#fff;
  left:42px;
}
.box p {
  margin:0;
}

<div class="box">
