Rendering issue with <tspan> and <style>

[jspobst]

A plotly figure I made isn't rendering correctly. The part that's failing involves a <tspan>, so I went and grabbed the simplest tspan example I could find from here to test further.

<svg viewBox="0 0 240 40" xmlns="http://www.w3.org/2000/svg">
  <style>
    text  { font: italic 12px serif; }
    tspan { font: bold 10px sans-serif; fill: red; }
  </style>

  <text x="10" y="30" class="small">
    You are
    <tspan>not</tspan>
    a banana!
  </text>
</svg>

That should produce

But when putting it through

drawing = svglib.svg2rlg(io.StringIO(textwrap.dedent(svg_string)))
renderPDF.draw(drawing, c, 50, 50)

I get this in the produced pdf

svglib: 1.3.0
reportlab: 3.6.9
python: 3.97
MacOS: 12.3.1

Thank you.

Thank you for raising your first issue! Your help to improve svglib is much appreciated!

Given that no text after not shows, it almost seems as though the </tspan> is somehow closing the <text>.

In #344, I tried to solve the issue of the trailing part of text nodes. The rendering of the sample above is not yet optimal, but at least it seems all text appear.

Hi @claudep, I see that this isn't optimal just yet, but I wanted to say thanks for the work you've already put into it so quickly. It really is appreciated!
