Overlapping Circles are not displayed correctly

[marenIFDCologne]

Hi there!

I tried to convert my own HTML-report to PDF. However some graphics I made from overlapping circles are not displayed correctly in the PDF.

I tried to convert the HTML with pdfkit.from_file() and pdfkit.from_string(), the outcome is the same.

This is the HTML, where the circles are displayed correctly:

This is the PDF-output:

Thanks in advance :)

I used the following code to create the circles:

.pie_outer {
  display: block;
  position: absolute;
  top: 0px;
  width: 100px;
  height: 100px;
  border-radius: 50%;
  background-image: conic-gradient( #474747 3deg, transparent 0);
  display: flex;
  justify-content: center;
  align-items: center;
}

.pie_inner_1 {
  display: block;
  width: 100px;
  height: 100px;
  border-radius: 50%;
  background-color: #b0b0b0;
  display: flex;
  justify-content: center;
  align-items: center;
}

.pie_inner_2 {
  display: block;
  position: absolute;
  top: 5px;
  left: 5px;
  width: 90px;
  height: 90px;
  border-radius: 50%;
  background-color: #b0b0b0;
  display: flex;
  justify-content: center;
  align-items: center;
}

.pie_punkte {
  font-size: 34px;
}

<div style="height:200px">
  <div id="pie_cat1" style="width:125px;position:absolute;top:420px;">
    <div class="pie_inner_1" id="pie_inner_1_cat1" style="background-color: rgb(211, 255, 224);"></div>

    </div>
    <div style="width:100px;position:absolute;top:100px;left:0px;">

    </div>
  </div>
</div>

pdfkit.from_file(input, output, verbose=True) created the following output:

Maybe display: flex is the problem.
I'm having an HTML with some elements with the flex property, and it doesn't render correctly.

I'm also facing the issue with display:flex, it's not being converted properly

any fixes for this?
