The bulid-validate-publish flow is failing.
E.g. https://github.com/gpuweb/gpuweb/actions/runs/3943724824/jobs/6748888303

make: *** Waiting for unfinished jobs....
LINE ~6751: No 'dfn' refs found for 'serializable objects' that are marked for export.
[=serializable objects=]
✘ Did not generate, due to fatal errors
make[1]: *** [Makefile:10: index.pre.html] Error 2

I think the problem is in spec/index.bs:

$ grep -n "serializable ob" index.bs
6751:{{GPUPipelineError}} objects are [=serializable objects=].
