Elixir region folding broken, because Elixir formatter requires all comments to match code indent.

Issue Type: Bug

In the following example code:

defmodule KV.Registry do
  use GenServer

  # region [ callbacks ]
  @impl true
  @spec init(:ok) :: {:ok, %{}}
  def init(:ok) do
    {:ok, %{}}
  end
  # endregion [callbacks]
end

the region is not foldable.

If the leading space before the region markers is removed, the regions become foldable, but the built-in, unconfigurable elixir formatter requires all comments to be indented to match code indent.

Interestingly, a single leading space does not break folding...
