Describe the bug
Excluding several comma-separated types of changes doesn't work in combination with --format json e.g. oasdiff diff --format json --exclude-elements=examples,description,title,summary spec1.yml spec2.yml

To Reproduce
Steps to reproduce the behavior:

1. Save test files

cat << EOF >| spec1.yml
components:
  schemas:
    Int:
      type: int
      description: Integer
EOF
cat << EOF >| spec2.yml
components:
  schemas:
    Int:
      type: int
      description: Integer.
EOF

2. Run oasdiff

$ oasdiff diff --format json --exclude-elements=description,title,summary
spec1.yml spec2.yml
{"extensions":{"modified":{"schemas":[{"oldValue":"Integer","value":"Integer.","op":"replace","from":"","path":"/Int/description"}]}},"components":{}}

Expected behavior
Description changes should be excluded. It worked last time I checked in oasdiff 1.10.16.

Desktop (please complete the following information):

• OS: Linux, oasdiff v1.11.1

Additional context
Filtering works if you skip --format json or pass only description to
--exclude-elements, that is both commands below work as expected, and filter
description change:

• oasdiff diff --exclude-elements description,title,summary spec1.yml spec2.yml
• oasdiff diff --format json --exclude-elements description spec1.yml spec2.yml
