If I run =3Demacs30 -Q=3D but alter the load path to use emacs28's nxml, it still hangs when I try to load the file with the long line. (Yes, this is a silly way to test if the bug is in nxml itself, but it was the quickest I could come up with.) In =3Demacs28 -Q=3D, when I try to load file, I see various errors, but it still load the file and I can edit it. Perhaps the bug is in fontification. Perhaps the bug is in how emacs handles whatever errors it is encountering when loading the file. The point is that whether it is a bug in emacs "in general", in nXML, or in glibc. The point is that there is a regression in how emacs behaves when loading this file with long lines. It "worked" better in Emacs28.
