Upstream fix (not merged yet): https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/408 I will do backport once it is approved and merged.
The upstream patch is broken, see: https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/408#note_2506947
Fixed that in the upstream merge request. Anyway, in my judgment, this is not important enough to worry about patching downstream. We'll pick up the fix in next upstream release.
