Oh, you're right. I mistakenly assumed Fedora used a default configuration, ran
"ldd /usr/bin/emacs", and saw libwebkit2gtk-4.0.so.37, so I thought WebKit2GTK
was in by default.

To get WebKit2GTK linked, one must configure Emacs with --with-xwidgets. Fedora
does that, so their x86 Emacs would require SSE2 if they still supported x86.
Which they do not - they dropped support for x86 in Fedora 31 (2019).
