Expected Behaviour

Using vim.lsp.buf.definition() to go to the definition of a local function variable (assigned with the = operator), should give only a single definition at the local variable name.

Actual Behaviour

Using vim.lsp.buf.definition() to go to the definition of a local function variable (assigned with the = operator), gives two definitions on the same line. One is located at the variable name and the other is located at the beginning of the function key word.

Reproduction steps

  1. Create a lua file with the following content:
local m = function() print "hello world" end

m()
  1. Move the cursor on the m() function call
  2. Execute the neovim command :lua vim.lsp.buf.definition()
