Elixir: Erlang/OTP 26 [erts-14.2.2] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [jit] Elixir 1.16.1 (compiled with Erlang/OTP 26)

Part of the source code:

    # |> Ecto.Multi.merge(fn %{insert_order: order} ->
    #   Ecto.Multi.new()
    #   |> Ecto.Multi.insert(:comment, Ecto.build_assoc(post, :comments))
    # end)
    |> Ecto.Multi.merge(fn %{insert_order: order} ->
      xupdate_meals(item_ids, order.updated_at)
    end)

Hovering over merge of the very first line containing # |> Ecto.Multi.merge gives following error:

@Terbium-135 I've been unable to replicate this. Can you give me the code that causes this, and the location where it happens?

I'm able to replicate this in vscode with the following snippet, representing | for the hover position:

defmodule Scratch do

  def a_humble_pipe(x) do
    ["a humble pipe", x]
  end

  def another_humble_pipe(x) do
    ["another_humble_pipe", x]
  end

  def many_such_pipes() do
    "pipe"
    |> a_humble_pipe()
    # |> ano|ther_humble_pipe()
    |> a_humble_pipe()
  end
end
