Problem with reusing the helpers object and nested helpers

[Akron]

In the following simple script I create a nested helper and try to access it multiple times using the helpers proxy object.

#!/usr/bin/env perl
use Mojolicious::Lite;

# Create nested helper
helper 'foo.bar' => sub {
  return 'Yeah!'
};

# Access nested helpers through proxy object multiple times
get '/' => sub {
  my $c = shift;
  my $h = $c->helpers;
  $c->render(text => $h->foo->bar . $h->foo->bar);
};

app->start('get','/');

This spits out the following error in recent Mojolicious (5.42):

Can't locate object method "foo" via package "Mojolicious::Renderer::Helpers::3e4a80e493b3a4d2be5bfe6cbbb678ee"

I may misuse the helpers object when using it multiple times ... but I am confused by the error. The error obviously doen't occur when I access $foo = $h->foo once and $foo->bar multiple times.
