Describe the bug

Documentation markdown is not rendered for ElixirLS.

Actual behavior

Expected behavior

To Reproduce

Reproducible always, for nvim 0.5 and 0.6 versions.

Possible reason - for Elixir files syntax is not set:

Closing, as issue is most probably with nvim-lsp and not related to nvim-compe.
