No suggestions for `@spec`ed function params

Environment

Elixir & Erlang versions (elixir --version):

Erlang/OTP 26 [erts-14.2.5.4] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit:ns]
Elixir 1.17.3 (compiled with Erlang/OTP 26)

VSCode ElixirLS version: v0.24.2
Operating System Version: Ubuntu 22.04.5 LTS

Troubleshooting

• Restart your editor (which will restart ElixirLS) sometimes fixes issues
• Stop your editor, remove the entire .elixir_ls directory, then restart your editor

Details

Given this code:

defmodule MyMod do
  @type t :: %MyMod{
          id: pos_integer(),
          name: binary()
        }
  defstruct id: 0,
            name: ""

  @spec hello1(person :: MyMod.t()) :: MyMod.t()
  defp hello1(person) do
    IO.inspect(person)
  end

  @spec hello2(person :: MyMod.t()) :: MyMod.t()
  defp hello2(%MyMod{} = person) do
    IO.inspect(person)
  end

  @spec hello3(person :: MyMod.t()) :: MyMod.t()
  defp hello3(person) do
    p1 = hello1(person)
    IO.inspect(p1)
  end

  def say_hello() do
    person = %MyMod{
      id: 123,
      name: "Bob"
    }

    hello1(person)
    hello2(person)
    hello3(person)
  end
end

Problem

Autocomplete/suggestions for the person variable do not work in the hello1() function

Expected result

Autocomplete/suggestions should work for the person variable in hello1() the same way they work in the hello2() function

Relevant info

Strangely enough, suggestions work for the p1 variable in the hello3() function
