Wrong diagnostics appearing on locationlist

[eemed]

Using rust_analyzer and NVIM v0.5.0-583-g7b529e791
This just seems very odd behavior.

My first asciinema

On start everything seems correct. After opening locationlist using :lopen it contains some arbitrary points in the file (they are always the same). Diagnostic signs disappear after a while on the locationlist. When the file buffer is refocused all of the signs and locationlist restore to normal. Removing any character or writing anything on the file buffer gets the arbitrary points back to location list.

Also on top of this is there a way to make locationlist report the error itself?

diagnostic-nvim configuration:

let g:diagnostic_insert_delay = 1

local nvim_lsp = require('nvim_lsp')

local on_attach = function(client, bufnr)
    require'diagnostic'.on_attach(client)

    vim.api.nvim_buf_set_option(bufnr, 'omnifunc', 'v:lua.vim.lsp.omnifunc')
    vim.api.nvim_command('setlocal signcolumn=yes')

    -- Mappings.
    local opts = { noremap=true, silent=true }
    vim.api.nvim_buf_set_keymap(bufnr , 'n' , 'gD'        , '<cmd>lua vim.lsp.buf.declaration()<CR>'            , opts)
