I'm reluctant to do that, because it would mean reintroducing
CVE-2021-30846, CVE-2021-30851 and CVE-2021-42762.  According to
<https://www.webkitgtk.org/security/WSA-2021-0006.html>, two of those
CVEs could allow an attacker to execute arbitrary code via maliciously
crafted web content.

For now, I've reverted back to using clang-11 to compile WebKitGTK,
which works correctly on x86_64-linux, but another fix will be needed to
i686-linux users.  I have some ideas on how to fix it.  I'll write about
that soon at 51591 <at> debbugs.gnu.org.

      Regards,
        Mark
