Problem with rendering text

[vincentfpgarcia]

Here is an input SVG image: https://upload.wikimedia.org/wikipedia/commons/7/7d/Roll_pitch_yaw_mnemonic.svg

When rendering it, the text is off:

The SVG code contains 2 tspan tags nested within a text tag.
By removing one tspan, the text displays correctly.

As pointed https://stackoverflow.com/questions/78807441/problem-with-text-rendering-using-cairosvg/78807953?noredirect=1#comment138959543_78807953, the problem might come from a bug in the interpretation of the text-anchor: middle style.

the problem might come from a bug in the interpretation of the text-anchor: middle style.

Yes, that’s exactly the problem.

As the bug doesn’t happen in WeasyPrint, that uses a code that’s close to CairoSVG’s code, I think that it’s fixed by Kozea/WeasyPrint@1460522 in WeasyPrint.

Would you like to try to backport it?
