the png image https://en.wikipedia.org/wiki/Command_pattern#/media/File:Command_pattern.svg which is a png has badly formed text but the svg source from which it is generated seems fine.

This seems to be about https://commons.wikimedia.org/wiki/File:Command_pattern.svg
Using newer librsvg2 2.46.3 locally and running rsvg-convert -h 645 -f png -o Command_pattern.png Command_pattern.svg, this still shows the same problem. Might be worth to report to upstream at https://gitlab.gnome.org/GNOME/librsvg/issues/
(For the records, the SVG itself looks correct in Chromium 78 and when using librsvg2 2.46.3. The SVG itself is incorrect in Firefox 70.)
I believe that this is just T36947, as this is a font size, hinting, and kerning problem. I generally find more issues with Liberation Sans (the default sans-serif) than Noto Sans, so it may be related to the font.
This issue is the same as T36947. Font sizes in original Command_Pattern.svg were below 5px.
