Indeed.  I pushed the patch below to `master` instead which should also
fix the problem.  Please confirm that it fixes it for you as well.
Maybe `eglot-shutdown` shouldn't end up calling
`eglot--signal-textDocument/didChange` at all, but that's a long
standing behavior AFAICT, so I'll leave it for some other time.
