Bug in Style/SymbolProc?

[bquorning]

In the RSpec documentation it is described how a stub can yield to the caller's block:

Taking that code and removing the argument to #call results in this code:

# encoding: utf-8
RSpec.describe 'When the caller passes a block' do
  it 'can be yielded to from your implementation block' do
    dbl = double
    allow(dbl).to receive(:foo) { |&block| block.call }
    expect { |probe| dbl.foo(&probe) }.to yield_control
  end
end

Running RuboCop v0.34.0 gives me this offense:

test.rb:5:19: C: Pass &:call as an argument to receive instead of a block.
    allow(dbl).to receive(:foo) { |&block| block.call }
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

RuboCop is happy if I change receive(:foo) { |&block| block.call } into receive(:foo, &:call), but it doesn’t work. I guess the cop doesn’t take the & in |&block| into consideration.
