Question: Correct rendered?

[JoKalliauer]

The first version in https://commons.wikimedia.org/wiki/File:D%C3%A9bit_de_Filtration_Glom%C3%A9rulaire.svg#filehistory is https://upload.wikimedia.org/wikipedia/commons/archive/e/e5/20200220180909%21D%C3%A9bit_de_Filtration_Glom%C3%A9rulaire.svg
(I already made a workaround, therefore a new version exists.)

Is rendered differently in rsvg and resvg.

rsvg	resvg

I personally assume resvg is right, since writing-mode= is not allowed in tspan(acording to validators), but however I do not know and reporting librsvg bugs has imho a low respondance-rate.

resvg is correct.

The ‘writing-mode’ property applies only to ‘text’ elements; the property is ignored for ‘tspan’, ‘tref’, ‘altGlyph’ and ‘textPath’ sub-elements.
