Elixir LS diagnostics not updating

[dvic]

Question: it seems like (maybe only sometimes) diagnostics are not updating after fixing an issue in my Elixir projects. I'm seeing the following logs:

2023-11-08T09:41:48.358 helix_lsp::transport [INFO] elixir-ls <- {"jsonrpc":"2.0","method":"textDocument/publishDiagnostics","params":{"diagnostics":[],"uri":"file:///Users/dvic/Development/pluto/lib/sentry_filter.ex","version":5}}
2023-11-08T09:41:48.358 helix_term::application [ERROR] received malformed notification from Language Server: Unhandled
2023-11-08T09:41:48.358 helix_term::application [INFO] Version (5) is out of date for "/Users/dvic/Development/pluto/lib/sentry_filter.ex" (expected (4), dropping PublishDiagnostic notification

Does anyone know if this is a known limitation or a bug? Or is it a bug in the Elixir language server?

With another language server (NextLS) the issue does not occur, as it's not sending the version. The check was added in this PR: #6282. Unless something comes to mind @pascalkuthe (author of that PR) I'll assume the issue lies with ElixirLS, I've opened elixir-lsp/elixir-ls#1024 to investigate further.
