I think it is a regression?  I tried the git blame interface in GNOME's
gitlab interface and the last commit that seems to touch the conditional
comments fun was from 4 months ago, and this commit is not in the 2.9.13
tag.

Git blame for the conditional comment fun:
https://gitlab.gnome.org/GNOME/libxml2/-/blame/master/parser.c#L6682

parser.c in 2.9.13 tag:
https://gitlab.gnome.org/GNOME/libxml2/-/blob/v2.9.13/parser.c

(see how it says last commit 5 months ago, whilst the latest relevant
commit according to git blame is 4 months ago.)
