ElixirLS debugger unexpectedly stops when used with Phoenix and VSCode

Question

Trying to debug my Phoenix project in VSCode using ElixirLS. The launch config is defined as

{
  "type": "mix_task",
  "name": "mix phx.server",
  "request": "launch",
  "task": "phx.server",
  "projectDir": "${workspaceRoot}"
}

The debugger starts and displays call stack for a fraction of a second but then immediately stops after "[info] Access TestAppWeb.Endpoint at http://localhost:4000" (see animated gif below). Has anyone gotten this to work?

Elixir 1.9.1

Seems like this issue is fixed in the fork of ElixirLS at https://github.com/elixir-lsp/elixir-ls .

The original repo doesn't have any commits since 10 Aug 2019, but the fork is pretty active.
