Logger report `callback_mode` for `gen_statem` changed in OTP27

Describe the bug
Since this change, the logger:report()
emitted by when gen_statem
crashes (when using callback_mode=handle_event_function
) has a different value for the callback_mode
key:
- it used to be the
handle_event_function
atom in OTP 26- - it is now the module's
fun Mod:handle_event/4
Not sure if this is a bug or intentional, feel free to close if it's the latter.
Just reporting in case it wasn't.
To Reproduce
(sorry in Elixir, taken from https://github.com/elixir-lang/elixir/pull/13684/files)
defmodule MyGenStatemFormatStatus do
@behaviour :gen_statem
@impl true
def callback_mode, do: :handle_event_function
@impl true
def init(state) do
{:ok, :no_state, state}
end
@impl true
def handle_event({:call, _}, :error, :no_state, _data) do
raise "oops"
end
end
Expected behavior
Perhaps it should be consistent with OTP26- and return handle_event_function
?
