Style/SpaceInsideBlockBraces doesn't add an offense for multi-line blocks

[owst]

We use Style/BlockDelimiters Enabled: false. For the following file:

> cat foo.rb
# encoding: utf-8
# frozen_string_literal: true

[1, 2, 3].map {|x|
  puts x + 1
}

[1, 2, 3].map {|x| puts x + 1 }

Rubocop only reports the missing space for the single-line block.

Expected behavior

Rubocop reports offenses for both blocks:

Inspecting 1 file
C

Offenses:

foo.rb:4:15: C: Space between { and | missing.
[1, 2, 3].map {|x|
              ^^
foo.rb:8:15: C: Space between { and | missing.
[1, 2, 3].map {|x| puts x + 1 }
              ^^

1 file inspected, 2 offenses detected

Actual behavior

Inspecting 1 file
C

Offenses:

foo.rb:8:15: C: Space between { and | missing.
[1, 2, 3].map {|x| puts x + 1 }
              ^^

1 file inspected, 1 offense detected

Steps to reproduce the problem

Run Rubocop on the provided file with Style/BlockDelimiters disabled.
